Si2493/57/34/15/04 FCC+ ISOmodem-EVB EVALUATION BOARD FOR THE Si2493/57/34/15/04 WITH A UART INTERFACE AND Si3008 LINE SIDE Description The FCC+ Si2493/57/34/15/04-EVB evaluation board provides the system designer an easy way of evaluating the Si2493/57/34/15/04 ISOmodem®. The Si2493/57/ 34/15/04-EVB consists of a motherboard with a power supply, an RS-232 and USB interface, other ease-ofuse features, and a complete removable modem module on a daughter card. (A functional block diagram of the Si2493/57/34/15/04-EVB is shown below.) The Si2493/57/34/15/04 ISOmodem® is a complete controller-based modem chipset with an integrated and programmable direct access arrangement (DAA) that meets the telephone line requirements for many countries. (See data sheet for details.) Available as a combination of one 8-pin line-side device and one 24pin or 16-pin system-side device, the Si2493/57/34/15/ 04 ISOmodem eliminates the need for a separate DSP data pump, modem controller, memories, codec, isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid. The Si2493/57/34/15/04 is ideal for embedded modem applications due to its small board area, controller-based architecture, and low power consumption. The Si2493/57/34/15/04-EVB provides an RJ-11 jack (for interfacing the Si2493/57/34/15/04-EVB to the phone line), and USB and RS232 serial ports for interfacing to a PC or data terminal. This allows the ISOmodem to operate as a serial modem for straightforward evaluation of the Si2493/57/34/15/04. To evaluate the Si2493/57/34/15/04 ISOmodem in an embedded system, the daughter card can be used independently of or with the motherboard. A direct access header (JP3) is available on the motherboard to
bypass the RS-232 transceivers and connect the Si2493/57/34/15/04 ISOmodem directly to a target system. An on-board rectifier, filter, and voltage regulator allow the power input to be 7.5–13 V ac or dc (either polarity) supplied through a screw terminal (J3) or a standard 2 mm power jack (J4). Alternatively, power can be supplied through the USB interface (whether the USB or RS232 interface is used). The evaluation board can drive an external speaker for call monitoring or the piezoelectric speaker mounted directly on the board. Please note that the PCM interface, EEPROM, and parallel interface options are available on the FT only. See "1.7.EVB Part Numbers" on page 5.
Features The Si2493/57/34/15/04-FT08FS08-EVB includes the following: Low cost Si3008 line-side device Dual RJ-11 connection to phone line RS-232 and USB interface to PC Piezoelectric speaker for call monitoring Direct access to Si2493/57/34/15/04 for embedded application evaluation Easy power connection to common 7.5 V–13.5 V power supplies or USB port. 9 V ac adaptor Support for daisy chain operation with Si3000 voice codec (FT only) Simple installation and operation EEPROM (FT only)

Si2493/57/34/15/04 FCC+ ISOmodem EVB 1. Si2493/57/34/15/04-EVB Setup and 1.2. Si2493/57/34/15/04-EVB Quick Start— USB Interface Evaluation This section explains how to set up the Si2493/57/34/ 15/04-EVB for evaluation as an RS-232 or USB interface modem. Jumper settings, power connection, PC/terminal connections, and terminal program configuration settings are given. The initial modem setup after power is applied as well as a basic tutorial on modem operation are provided. Si2493/57/34/15/04EVB configurations for evaluating additional features are discussed separately. See the Si2493/57/34/15-08 or Si2404-08 data sheets for complete details.

Si2493/57/34/15/04 FCC+ ISOmodem EVB 1.4. Power Requirements The Si2493/57/34/15/04-EVB has an on-board diode bridge, filter capacitor, and voltage regulator (U1). Power can be supplied from any source capable of providing 7.5 V–13 V dc or 7.5 V–13 V peak ac and at least 100 mA. (Additional current may be required if a speaker is connected for monitoring call progress tones.) Power may be applied to the Si2493/57/34/15/ 04-EVB through the screw terminals (J3), the 2 mm power jack (J4), or the USB cable (even if the modem is configured for RS-232 operation). The onboard fullwave rectifier and filter ensure the correct polarity is applied to the Si2493/57/34/15/04-EVB. Daughter card power is supplied through voltage regulator U2 by connecting JP7, pins 1 and 2. Daughter card current can be measured by connecting an ammeter between JP7, pins 1 and 2. Failure to connect pins 1 and 2 of JP7 through either a jumper or a low-impedance ammeter may result in damage to the Si2493/57/34/15/ 04-EVB.
1.5. Terminal and Line Connections The Si2493/57/34/15/04 can be tested as a standard serial data modem by connecting the Si2493/57/34/15/ 04-EVB to a personal computer or other data terminal equipment (DTE), phone line, and power. Connect a PC serial port to the DB9 connector on the Si2493/57/34/ 15/04-EVB with a pass-through cable. The RS-232 transceivers on the EVB can communicate with the DTE at rates up to 1 Mbps. Any standard terminal program, such as HyperTerminal or ProComm, running on a PC communicates with the Si2493/57/34/15/04-EVB. The standard factory jumper configuration has autobaud enabled. Autobaud detects the DTE speed, data length, parity, and number of stop bits. If JP9 is installed, autobaud is disabled. Configure the terminal emulation program to 19200 bps, eight data bits, no parity, one stop bit, and hardware (CTS) handshaking. Connect the RJ-11 jack on the Si2493/57/ 34/15/04-EVB to an analog phone line or telephone line simulator, such as a Teltone TLS 5.
The modem should respond with “2493”, “2457”, “2434”, “2415”, or “2404” indicating the terminal is communicating with an Si2493, Si2457, Si2434, Si2415, or Si2404. Type “ATS0=2
” to configure the modem to answer on the second ring. To take the modem off-hook, type “ATH1.” The modem should go to the off-hook state, draw loop current, and respond with an “OK.” Next, type “ATH” or “ATH0”, and the modem should hang up (go on-hook) and stop drawing loop current. To make a modem connection, type “ATDT(called modem phone number).” Once the connection is established, a “CONNECT” message appears indicating the two modems are in the data mode and communicating. Typing on one terminal should appear on the other terminal. To return to the command mode without interrupting the connection between the two modems, type “+++.” Approximately two seconds later, “OK” appears. The modem is now in command mode and accepts “AT” commands.Type “ATH” (or “ATH0”) to terminate the data connection, or type “ATO” to return to the data mode. After the ATO command, the modem resumes the data connection and no longer accepts AT commands.
1.7. EVB Part Numbers The ISOmodem evaluation boards are offered in multiple speeds and packaging options. The first four numbers indicate the system-side device. The next two letters indicate the system-side package (FS–Lead-free, 16-pin SOIC; FT–Lead-free, 24-pin TSSOP). The final two numbers indicate the line-side device. See Figure 5.

Figure 5. EVB Part Number Example
With the terminal program properly configured and running, apply power to the Si2493/57/34/15/04-EVB. Type “AT”, and the modem should return “OK” indicating the modem is working in the command mode and communicating with the terminal. If the “OK” response is not received, try resetting the modem by pressing the manual reset switch (S1); then, again type “AT.” Next, type “ATI6.”
2. Si2493/57/34/15/04-EVB Functional Description The Si2493/57/34/15/04-EVB is a multipurpose evaluation system. The modem daughter card illustrates the small size and few components required to implement an entire controller-based modem with global compatibility. The daughter card can be used independently of, or in conjunction with, the motherboard. The motherboard adds features that

Si2493/57/34/15/04 FCC+ ISOmodem EVB enhance the ease of evaluating the many capabilities of the Si2493/57/34/15/04 ISOmodem®.
2.1. Motherboard The motherboard provides a convenient interface to the Si2493/57/34/15/04-08DC (daughter card). The versatile power supply allows for a wide range of ac and dc voltages to power the board. RS-232 transceivers and a DB9 connector allow the Si2493/57/34/15/04EVB to be easily connected to a PC or other terminal device. Jumper options allow direct access to the LVCMOS/TTL level serial inputs to the Si2493/57/34/15/ 04, bypassing the RS-232 transceivers or USB interface. This is particularly useful for directly connecting the Si2493/57/34/15/04 to embedded systems. The Si24xx-08URT-EVB motherboard connects to the daughter card through two connectors, JP1 and JP2. JP1 is an 8x2 socket providing connection to all Si2493/ 57/34/15/04 digital signals and regulated 3.3 V power for the Si2493/57/34/15/04. The Si2493/57/34/15/04 digital signals appearing at JP1 (daughter card interface) are LVCMOS and TTL compatible. The Si2493/57/34/15/04-08 daughter card must be powered by 3.3 V. The motherboard is factory configured for 3.3 V with JP7. JP2 is a 4x1 socket providing connection between the daughter card and the RJ-11 phone jack.
that RESET be controlled by the host processor. Certain Si2493/57/34/15/04 operation modes, including powerdown, require a hardware reset to recover. The Si2493/57/34/15/04-EVB contains two reset options, an automatic power-on reset device, U3 (DS1818) (default), and a manual reset switch (S1) to permit resetting the chip without removing power. A reset, regardless of the mechanism, causes all modem settings to revert to factory default values. See Figure 13 on page 17 and Figure 15 on page 19 for the reset circuit schematic. 2.1.3. DS1818 The DS1818 is a small, low-cost device that monitors the voltage on VD and an external reset pushbutton. If VD drops below 3.0 V, the DS1818 provides a 220 ms active-low reset pulse. On powerup, the DS1818 also outputs an active low reset pulse for 220 ms after VD reaches 90% of the nominal 3.3 V value. The DS1818 outputs a 220 ms reset pulse any time the power supply voltage exceeds the 3.3 V ±10% window. 2.1.4. Manual Reset The manual reset switch (S1) performs a power-on reset. This resets the Si2493/57/34/15/04 to factory defaults without turning off power. If S1 is used in conjunction with U3, pressing S1 activates the reset monitor in the DS1818 and produces a 220 ms active low reset pulse.
2.1.1. Voltage Regulator/Power Supply
2.1.5. EEPROM Enable (FT Only)
The input voltage to either J3 or J4 must be between 7.5 and 13.5 V dc or 7.5 and 13.5 VPEAK ac. The motherboard includes a diode bridge (D1–D4) to guard against a polarity reversal of the dc voltage or to rectify an ac voltage. The power source must be capable of continuously supplying at least 100 mA. C6 serves as a filter cap for an ac input. The voltage regulator, U1, provides 5 V for the motherboard and the input for voltage regulator U2, which outputs 3.3 V for use on the motherboard and to power the daughter card. Si24xxDC power consumption can be measured by placing a meter between pins 1 and 2 of JP7. The connection between JP7 pins 1 and 2 must be made at all times when power is applied to the evaluation board either through a jumper block or a low-impedance meter to avoid damage to the daughter card. Power is supplied to U2 through D5 from the USB.
Connecting JP10 enables the optional EEPROM, U9. See “AN93: Si2457/Si2434/Si2415/Si2404 Modem Designer’s Guide” for programming details.
2.1.2. Reset Circuitry The Si2493/57/34/15/04 requires a reset pulse to remain low for at least 5.0 ms after the power supply has stabilized during the powerup sequence or for at least 5.0 ms during a power-on reset. Most production Si2493/57/34/15/04 modem chipset applications require

2.1.6. Interface Selection The serial interface of the Si2493/57/34/15/04-EVB can be connected to a computer, terminal, embedded system, or any other data terminal equipment (DTE) via a standard RS-232 interface, USB interface, or through a direct TTL serial interface. The Si2493/57/34/15/04 can be tested as a standard data modem by connecting the Si2493/57/34/15/04EVB to a personal computer or other DTE power supply and a phone line. A PC can communicate with the Si2493/57/34/15/04-EVB using a standard terminal program, such as HyperTerm or ProComm. Jumper settings determine how the Si2493/57/34/15/ 04-EVB is connected to the DTE. Table 1 lists the interface controlled by each motherboard jumper. See Figure 14 on page 18 and Figure 26 on page 30.

Si2493/57/34/15/04 FCC+ ISOmodem EVB 34/15/04 and, using internal charge pumps, makes these signals compatible with the RS-232 standard. The RS-232 transceiver on the Si2493/57/34/15/04-EVB can communicate at rates between 300 bps and 1 Mbps. This simplifies the connection to PCs and other data terminal equipment (DTE). The signals available on the Si2493/57/34/15/04-EVB serial interface (DB9 connector) are listed in Table 2.

2.1.8. USB Interface The USB cable connects to J5 on the motherboard and provides both data and power. Installing a jumper on JP5 enables the USB interface and disables the RS-232 interface. The USB interface is provided by U5. A USB driver for this chip is available for most PC and MAC operating systems on the CD. 2.1.9. Direct Access Interface The motherboard supplies power through J3, J4, or USB, power-on reset, and an RJ-11 jack for the modem. The direct access interface (JP3) is used to connect the motherboard to an embedded system. JP3 provides access to all Si2493/57/34/15/04 signals available on the daughter card. It is necessary to install a jumper on JP8 to disable both the RS-232 and USB interface and prevent signal contention. Leave the jumper between JP7 pins 1 and 2. Figures 6 and 7 illustrate the jumper settings required for the direct access mode using the motherboard.

Si2493/57/34/15/04 FCC+ ISOmodem EVB To use voice mode register U71 and data memory location 0x0059 must be properly configured. Setting data memory 0x0059 = 0x0001 enables the Si24XX TDMA interface. When U71 is set to the value 0x0011 a 16-bit voice sample is transmitted from the Si3000 through the Si2493/57/34/15/04 and DAA to the remote device. Likewise, an analog signal from the remote device passes through the DAA where it is converted to a 16-bit voice sample, the Si24xx, and finally the Si3000 where it is converted back to the analog receive signal. In this example, the Si3000 has its digital TDMA interface configured as the Slave Serial Mode by adding a 50 kΩ pulldown resistor to SDO pin and a pullup 50 kΩ resistor to SCLK pin.
In this mode, the Si3000’s MCLK is driven by the 2048 kHz clock from Si2493/57/34/15/04. The FSYNC has an 8 kHz pulse input. The bit clock is 2048/8 = 256 bits per frame sync. Refer to the Si3000 documentation for further details. To send control information to the Si3000, the Si2493/ 57/34/15/04 modem chip provides a PCM control port 0x004B that allows the user to send control words across by using the AT memory write command. See Table 4. for details. Wait for the “OK” (approximately 300 ms after each command). When a connection is established, the “AT.” command is used to generate the DTMF tone of a number; For example, AT.3 generates a number 3 DTMF tone without the need for an external DTMF generator. See "2.2.Voice Mode Example" on page 12 for details.

Si2493/57/34/15/04 FCC+ ISOmodem EVB 2.2. Voice Mode Example Perform the following steps: 1. Connect hardware as shown in Figure 8 on page 9. Note that the Si3000 Evaluation Board requires an external 12 V supply and derives 5 V power from the Si24xx-EVB. The Si24xx-EVB should be connected to the supplied power adapter or powered through USB. 2. Enter the following AT commands to initialize the modem:
ATZ
reset modem
ATE0
disable echo
AT:U0071,11
enable voice routing firmware
AT*Y254:W0059,7785
enable Si3000 Hardware Interface In actual application, this line must be implemented as a read-modifywrite consisting of the following: n = AT*Y254:Q0059 n |= 1 AT*Y254:W0059,n
AT*Y254:W004B,011C
Si3000 Reg 01 = 1C This applies power to SPKRx,HDST,LINEO
AT*Y254:W004B,0545
Si3000 Reg 05 = 45 Enable HDST into ADC mixer MIC input disabled LINEI input disabled
AT*Y254:W004B,065D
Si3000 Reg 06 = 6D Activate HDST as output Keep LINEO muted
0 db Receive Gain Setting AT*Y254:W004B,075CSi3000 Reg 07 = 5C 0 dB Transmit Gain Keep SPKRx muted 3. Type "ATDTnnn", where nnn represents the telephone number of the remote telephone. 4. The remote phone rings and should be picked up. 5. Also pick up the local phone connected to the Si3000 Evaluation Board. 6. At this point, a voice connection exists between the two telephones. 7. It is also possible to send a series of single digit DTMF tones to the remote phone using the "AT.N" command (dot character is in-between "AT" and "N", where N is a DTMF digit 0-9,A-F). Example: AT.1 sends DTMF digit 1, return to voice mode.

Si2493/57/34/15/04 FCC+ ISOmodem EVB 2.2.1. Audio Output Audio output is provided from the Si2457/34/15 on the AOUT pin. This signal allows the user to monitor call progress signals, such as dial tone, DTMF dialing, ring, busy signals, and modem negotiation. Control of this signal is provided by AT commands and register settings described in the introduction. The AOUT signal can be connected to an amplifier, such as the LM386 (the default stuffing option on the Si2457/34/15URTEVB), for high-quality output. AOUT can also be connected to a summing amplifier or multiplexer in an embedded application as part of an integrated audio system.
The daughter card requires a 3.3 V supply capable of providing at least 35 mA and communicates with the system via LVCMOS/TTL-compatible digital signals on JP1. The RJ-11 jack (TIP and RING) is connected via JP2. Be sure to provide the proper power-on reset pulse to the daughter card if it is used in the stand-alone mode. 2.3.1. Reset Requirements The Si2457/34/15 ISOmodem® daughter card must be properly reset at powerup. The reset pin (pin 8) of the Si2457/34/15 (JP1, pin 13) must be held low for at least 5.0 ms after power is applied and stabilized to ensure the device is properly reset.
2.2.2. Amplifier (LM386)
2.3.2. Crystal Requirements
The audio amplifier circuit consists of U10 (LM386), C20, R3, R4, C21, C22, C23, R5, C24, and an optional loudspeaker, LS1. The LM386 has an internally-set voltage gain of 20. R3 and R4 provide a voltage divider to reduce the AOUT signal to prevent overdriving the LM386. C20 provides dc blocking for the input signal and forms a high-pass filter with R3+R4 while R4 and C21 form a low-pass filter. These four components limit the bandwidth of the AOUT signal. C22 provides highfrequency power supply bypassing for the LM386 and should be connected to a hard ground and located very close to the amplifier’s power supply and ground pins. C23 and R5 form a compensation circuit to prevent oscillation of the high current PNP transistor in the LM386 output stage on negative signal peaks. These oscillations can occur between 2–5 MHz and can pose a radiation compliance problem if C23 and R5 are omitted. C24 provides dc blocking for the output of the LM386, which is biased at approximately 2.5 V (VCC/2), and forms a high-pass filter with the impedance of the loudspeaker (LS1). The output from the LM386 amplifier circuit is available on the RCA jack, J2 (not installed). Install jumper JP13 to enable the on-board speaker, LS1.
Clock accuracy and stability are important in modem applications. To ensure reliable communication between modems, the clock must remain within ±100 ppm of the design value over the life of the modem. The crystal selected for use in a modem application must have a frequency tolerance of less than ±100 ppm for the combination of initial frequency tolerance, drift over the normal operating temperature range, and five year aging. Other considerations, such as production variations in PC board capacitance and the tolerance of loading capacitors, must also be taken into account.
2.3. Modem Module Operation The Si2457/34/15URT-EVB daughter card is a complete modem solution perfectly suited for use in an embedded system.
2.3.3. Protection The Si2493/57/34/15/04-EVB meets or exceeds all FCC and international PTT requirements and recommendations for high-voltage surge and isolation testing without any modification. The protection/isolation circuitry includes C1, C2, C8, C9, FB1, FB2, and RV1. The PCB layout is also a key “component” in the protection circuitry. The Si2493/57/34/15/04-EVB provides isolation to 3 kV. Contact Silicon Laboratories for information about designing to higher levels of isolation.
3. Design The following sections contain the schematics, bill of materials, and layout for the Si2493/57/34/15/04 including the daughter card and motherboard.
