Section 1
Functional description
The PLRXPL-Sx-VGx-xx-x transceiver is designed to transmit and receive 8B/10B encoded serial optical data over 9/125 µm optical fiber.
Transmitter The transmitter converts 8B/10B encoded serial PECL/CML electrical data into serial optical data meeting the requirements of Fibre Channel 400/200/100-SM-LC specifications. Transmit data lines (TD+ & TD-) are internally AC coupled with 100 Ω differential termination. An open collector compatible Transmit Disable (TDis) is provided. This pin is internally terminated with a 10 kΩ resistor to VccT. A logic “1,” or no connection on this pin will disable the laser from transmitting. A logic “0” on this pin provides normal operation. The transmitter has an internal PIN monitor diode that is used to ensure constant optical power output across supply voltage and is used to temperature control the laser output power to ensure higher reliability at high temperature. An open collector compatible Transmit Fault (TFault) is provided. The Transmit Fault signal must be pulled high on the host board for proper operation. A logic “1” output from this pin indicates that a transmitter fault has occurred, or the part is not fully seated and the transmitter is disabled. A logic “0” on this pin indicates normal operation.
Receiver The receiver converts 8B/10B encoded serial optical data into serial PECL/CML electrical data. Receive data lines (RD+ & RD-) are internally AC coupled with 100 Ω differential source impedance, and must be terminated with a 100 Ω differential load. Rate select, pin 7, switches the receiver bandwith enabling superior performance at 4.25 Gbps, 2.125 Gbps, and 1.0625 Gbps line rates. With non rate-select parts or when rate-select is set “high” (4.25/ 2.125 Gbps mode) on rate-select part numbers, the receiver bandwidth is not compliant to the maximum receiver bandwidth specified under 100-SM-LC-L.

An open collector compatible Loss of Signal is provided. The LOS must be pulled high on the host board for proper operation. A logic “0” indicates that light has been detected at the input to the receiver (see Section 3.4 Optical characteristic, LOS Assert/Deassert Time on page 9). A logic “1” output indicates that insufficient light has been detected for proper operation. Power supply filtering is recommended for both the transmitter and receiver. Filtering should be placed on the host assembly as close to the Vcc pins as possible for optimal performance.

Notes
Power supply filtering components should be placed as close to the Vcc pins of the host connector as possible for optimal performance.
PECL driver and receiver will require biasing networks. Please consult application notes from suppliers of these components.
MOD_DEF(2) and MOD_DEF(1) should be bi-directional open collector connections in order to implement serial ID (MOD_DEF[0,1,1]) PLRXPL-Sx-VGx-xx-x transceiver.
*
Transmission lines should be 100 Ω differential traces. It is recommended that the termination resistor for the PECL Receiver (R3 + R4) be placed beyond the input pins of the PECL Receiver. Series Source Termination Resistors on the PECL Driver (R1+R2) should be placed as close to the driver output pins as possible.

4.1 Digital Diagnostic Monitoring and Serial ID Operation The PLRXPL-Sx-VGx-xx-x is equipped with a 2-wire serial EEPROM that is used to store specific information about the type/identification of the transceiver as well as real-time digitized information relating to the transceiver’s performance. See Section IV, “Module Definition Interface and Data Field Description” of the SFP-MSA Pin Definitions and Host Board Layout document for memory/address organization of the identification data and the Small Form Factor Commitee’s document number SFF8472 Rev 9.5, dated June 1, 2004, for memory/address organization of the digital diagnostic data. To communicate to the module it is required that the host clock either be running at 100kHz or less (per the SFP MSA) or implementing Clock Stretching per the 2-wire serial interface protocol.

The enhanced digital diagnostics feature monitors five key transceiver parameters which are Internally Calibrated and should be read as absolute values and interpreted as follows; Transceiver Temperature in degrees Celsius: Internally measured. Represented as a 16 bit signed two’s complement value in increments of 1/256 degrees Celsius from -40 to +125°C with LSB equal to 1/256 degrees C. Accuracy is ± 3 degrees Celsius over the specified operating temperature and voltage range. Vcc/Supply Voltage in Volts: Internally measured. Represented as a 16 bit unsigned integer with the voltage defined as the full 16 bit value(0-65535) with LSB equal to 100µV with a measurement range of 0 to +6.55V. Accuracy is ± 3% of nominal value over the specified operating temperature and voltage ranges. TX Bias Current in µΑ: Represented as a 16 bit unsigned integer with current defined as the full 16 bit value(0-65535) with LSB equal to 2µΑ with a measurement range of 0 - 131mA. Accuracy is ± 10% of nominal value over the specified operating temperature and voltage ranges. TX Output Power in mW: Represented as a 16 bit unsigned integer with the power defined as the full 16 bit value (0-65535) with LSB equal to 0.1µW. Accuracy is ± 2dB over the specified temperature and voltage ranges over the permitted range of 87µW to 500µW( -10.6dBm to -3dBm). Data is not valid when transmitter is disabled. RX Received Optical Power in mW: Represented as average power as a 16 bit unsigned integer with the power defined as the full 16 bit value(0-65535) with LSB equal to 0.1µW. Accuracy is ± 3dB over the specified temperature and voltage ranges over the power range of 10µW to 800µW (-20dBm to 1dBm).
Reading the data The information is accessed through the MOD_DEF(1), and MOD_DEF(2) connector pins of the module. The specification for this EEPROM (ATMEL AT24CO1A family) contains all the timing and addressing information required for accessing the data. The device address used to read the Serial ID data is 1010000X(A0h), and the address to read the diagnostic data is 1010001X(A2h). Any other device addresses will be ignored. Refer to Figure 4, Figure 5, and Figure 6 for information regarding addresses and data field descriptions MOD_DEF(0), pin 6 on the transceiver, is connected to Logic 0 (Ground) on the transceiver. MOD_DEF(1), pin 5 on the transceiver, is connected to the SCL pin of the EEPROM. MOD_DEF(2), pin 4 on the transceiver, is connected to the SDA pin of the EEPROM. Write access is only allowed to the customer-writable field(bytes 128-247 of address 1010001X).
Decoding the data The information stored in the EEPROM including organization is defined in the Small Form-Factor Pluggable Multisource (SFP-MSA) Pin Definitions and Host Board Layout document, dated 3/13/00, Section IV. The digital diagnostic information stored in the EEPROM is defined in the Small FormFactor document SFF-8472 draft rev 9.5, dated 6/1/04.

4.2 Package and handling instructions Process plug The PLRXPL-Sx-VGx-xx-x is supplied with a dust cover. This plug protects the transceiver’s optics during standard manufacturing processes by preventing contamination from air borne particles. Note:
It is recommended that the dust cover remain in the transceiver whenever an optical fiber connector is not inserted.
Recommended cleaning and de-greasing chemicals Picolight recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning. Do not use halogenated hydrocarbons (e.g. trichloroethane, ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).
Flammability The PLRXPL-Sx-VGx-xx-x housing is made of cast zinc.
4.3 ESD discharge (ESD) Handling Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from packaging and handled only in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps. March 2006

Test and operation In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements. Typical of optical transceivers, this module’s receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event might require that the application re-acquire synchronization at the higher layers (e.g. Serializer/Deserializer chip).
4.4 Eye safety The PLRXPL-Sx-VGx-xx-x is an international Class 1 laser product per IEC 825-2: 1997, and per CDRH, 21 CFR 1040 Laser Safety Requirements. The PLRXPL-Sx-VGx-xx-x is an eye safe device when operated within the limits of this specification. Operating this product in a manner inconsistent with intended usage and specification may result in hazardous radiation exposure.
CAUTION! Tampering with this laser based product or operating this product outside the limits of this specification may be considered an act of “manufacturing,” and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (21 CFR 1040).
