dc2159af is a usb interface circuit provided by linear technology company for connecting fmc compatible fpga evaluation board.
The DC2159A demonstration circuit provides USB connectivity to an FMC compatible FPGA evaluation board via an FT2232H Dual USB UART/FIFO. It is used with various FPGA boards and a Linear Technology data converter evaluation board as part of an evaluation system.
The demo manual gives a quick start procedure, including seating the FMC connector, installing two 4-40 nuts, checking SW1 is in the SPI position, and inserting the USB cable only after the FPGA board is powered up. It also documents the JTAG port, other connections, the parts list and the schematic diagram.
| Host interface | USB connectivity via FT2232H Dual USB UART/FIFO |
|---|---|
| FPGA connection | FMC compatible FPGA evaluation board |
| USB connector | Mini USB 2.0 Type B, right angle |
| FMC connector | BGA connector, 40x10 |
It provides USB connectivity to an FMC compatible FPGA evaluation board via an FT2232H Dual USB UART/FIFO.
Only after the FPGA board is powered up; the manual warns that inserting it earlier can cause incorrect identification.
SW1 should be in the SPI position.
It provides a JTAG connection that may be used in some evaluation setups; refer to the data converter’s demo manual.
