Insight - Xilinix SpartanII FPGA Development Board with a Spartan XC2S100 device. A Maxim MAX3094 dual RS422 receiver IC and Future
Technology Devices International FT245R FIFO USB module is wired in the prototype area.
The output of the CM701 modem goes to the RS422 receiver on the FPGA board. The FPGA acquires frame sync, performs the
data stream PN decode and writes the data to the USB FIFO module.
