I want to use Genesys-2 FPGA board as a BER tester for transceiver circuits. I am using IBERT IP core available in Vivado for it. Genesys-2 has an FMC connector to provide output for which I am using SMA-FMC-LVDS of Hightech Global to convert the data from FMC to SMA. Initially, I am connecting transmitter and receiver in loopback just for verification.
The problem is: 1. In loopback connection, in Vivado I am unable to see any transmission. It is only displaying 0Gbps. 2. Previously I have used different SMA-FMC board for which transmission was proper and I was able to measure the BER. By this, it is clear that there is no problem with the code. 3. In the SMA-FMC-LVDS a place holder is provided for an external oscillator. Do I need to solder this oscillator for proper transmission?
I can not find any supporting document for the configuration of SMA-FMC-LVDS.
