Table 7. Audio FMC Connections

There are 4 SMA audio connectors J1 through J4. The silkscreen calls out the positive and negative sides

for Rx and Tx, however, these are straight through connections to the FMC, which allows the designer to

use them as he/she sees fit.

PMOD connectors: Two 12 pin “Dual” PMOD connectors are available on JA and JC, and a single 6 pin

PMOD is available on JB. These connectors are intended as connection points for Digilent's expansion

boards. The voltage, as always, represents the FPGA’s input and output voltage. There are voltage

translators on the FMC-CE card that translate the PMOD’s I/O to 3.3V.
