DESCRIPTION
FMC Communication
Interface
Introduction
Demonstration circuit 2159 provides USB connectivity to
an FMC compatible FPGA evaluation board via an FT2232H
Dual USB UART/FIFO. It is used in conjunction with vari-
ous FPGA boards and a Linear Technology data converter
evaluation board as part of an evaluation system for Linear
Technology products.

QUICK START PROCEDURE
Make sure FPGA board power is OFF and no USB cable
is connected. Seat the FMC connector on the back side
of DC2159 to the mating connector on the FPGA board,
pressing evenly across the connector and providing sup-
port on the back side of the FPGA board. Install two 4-40
nuts on the two standoffs to secure the connection. Verify
that SW1 is in the SPI position.
Follow any additional setup instructions for the data con-
verter board (For example, DC1974 shown in Figure 2.)
Only insert the USB cable AFTER the FPGA board is pow-
ered up. (The FT2232 I/O power is only enabled when the
FPGA board is powered up; inserting the USB cable without
I/O power causes incorrect identification of the FT2232.)
JTAG Port
J2 provides a JTAG connection that may be used in some
evaluation setups. Refer to the data converter’s demo
manual.
Other Connections
All test points are for factory use only. Do not make any
other connections.
