This compact 4.3" x 4.4" software radio is configured to implement a dual-mode Satellite/Terrestrial Receiver from the Analog/Digital converters to the stereo audio output.

More specifically, this design embodies the following functions:

- baseband processing for three channel receiver

- DSP audio decoder

- audio interface

- automotive power conditioning

- user interface over serial link

In addition to the FPGA and DSP, the design emphasizes glue-less interface to a limited number of commercially available parts:

• two 10-bit A/D converters

• Lucent 16210 DSP

• low-cost crystal (+/- 100ppm), no TCXO required

• one external SRAM 100ns 512K x 8

• one external SDRAM 8 MB.

The design is consistent with a single frequency down-conversion.

The board's purpose is to validate the receiver VHDL code before ASIC manufacturing.

The current code size is 1.7 Million gates.
