ADS54J54: Qustion about PCB material

Ramin Fardi

Part Number: ADS54J54
Other Parts Discussed in Thread: TSW14J50EVM,

Hi,

Have you ever qualified ADS54J54 on FR4 PCB? We are doing a board very similar to ADS54J54EVM i.e 500MHz sampling clock on 4 channels with 2 JESD204B Lanes per channel (5Gbps/lane). What I can see you use Magtron 6 for ADC board (lanes are approx. 100mm long to the FMC connector) and FR4 for FPGA board TSW14J50EVM (lanes are much shorter). Our lanes are going to be 50mm long. Could we use FR4? 

By the way is there any equalization going on on any side of the link on the EVMs?

Regards/Ramin
