Technology for Innovators TM Product Bulletin Key Benefits • Small form factor for easy portability • Self-contained • Embedded, independent power monitoring for each processor • Seamless hardware and software integration from baseband to antenna • Supports model-based design tools, accelerating prototyping • Integrated troubleshooting and hardware-in-the-loop co-verification capabilities • The platform incorporates GPP, DSP and FPGA, making it easy to implement all protocol layers for a complete radio • Easy adoption of third-party RF and I/O boards • Ethernet remote access capabilities SFF SDR Development Platform Overview Potential Applications The Small Form Factor (SFF) Software-Defined Radio (SDR) Development Platform is a unique new product that addresses the special portable SDR needs of public safety and commercial markets. It was designed around the latest DSP and FPGA technology as a low-cost, off-the-shelf, integrated hardware and software development solution. The SFF SDR Development Platform is separated into three distinct modules — the Digital Processing Module, Data Conversion Module and RF Module — offering developers highly flexible development capabilities. The following applications will benefit greatly from using the SFF SDR Development Platform. Public safety • Such public safety applications as TETRA and APCO band communications, vehicular systems, transponders and broadband data systems will be greatly enhanced by their use of the SFF SDR Development Platform. Commercial • RFID readers, WiMAX and Wi-Fi customer-premises equipment (CPE), broadband data systems, vehicular systems, as well as femto and pico base stations are but a few applications that can be developed with the SFF SDR Development Platform. • • • Key Features The SFF SDR Development Platform includes the following leadingedge features: • TMS320DM6446 DSP system-onchip from Texas Instruments • TMS320C64x+™ DSP core, 594 MHz • • • • • ARM926 core, 297 MHz • Rich set of peripherals including serial ports, USB, EMAC, DDR2 EMIF, as well as video ports Virtex-4 SX35 FPGA from Xilinx ADS5500, 125-MSPS, 14-bit dual-channel analog-to-digital converter from Texas Instruments DAC5687, 500-MSPS, 16-bit dual-channel digital-to-analog converter from Texas Instruments Selection of bandwidth (5 MHz or 20 MHz) Modular — allows additional boards to be stacked RF module operating between 360 MHz and 960 MHz Optional supports of a second RF module for full-duplex operation or to cover additional bands • Boot loader located in the flash memory for autonomous use of the platform JTAG Data Conversion Module Expansion Port RS-232 Transceiver VPFE 32 Bits TMS320DM6446 FPGA (Virtex-4) 32-Bit, Async Control DB-9 VPBE VPBE VPFE 32-Bit, Sync FIFO_B USB 2.0 (Host or Slave) EMAC Ethernet PHY 10/100 16-bit EMIF/ MMC/ VLYNQ SD SD Card NAND Flash Memory (1 Gb, 8 Bits) 16-bit EMIF/ VLYNQ DDR2 SDRAM (128 MB) USB 2.0 2 × McBSP RJ-45 12 V, –12 V, 5 V, 3.3 V Mic In 1/8” Jack LED (5) DIP Switches (5) Buttons (4) GPIO (28) PCM3008 Codec Stereo, 16 Bits, 48 kHz ASP Line In 1/8” Jack Line Out 1/8” Jack JTAG JTAG 5V 12-V DC In Power 1.8-V DDR Management 3.3 V Voltage/ Current Monitoring MSP430 Power Jack 1.2-V DM644x FPGA Vcore Digital Processing Module DAC5687 Dual, 16-Bit, 500-MSPS DAC Digital ext.
