FtxlHal.c.
Other Hardware Design Considerations
The FTXL 3190 Free Topology Smart Transceiver Chip shares electrical and
physical characteristics with the FT 3120 Smart Transceiver Chip. For
information about hardware design for an FT 3120 Smart Transceiver, including
PCB design considerations, EMC considerations, electrical characteristics of the
chip, and networking requirements, see the FT 3120 / FT 3150 Smart
Transceiver Data Book .
For other FPGA design considerations, see the Altera Cyclone II Device
Handbook or the Cyclone III Device Handbook .
