FPGA with CML IO

Hi, I am looking for an FPGA / SOC having CML I/O that can accept high speed ADC data.

Hello,

Xilinx 7-series family of FPGAs has such CML I/O.

Do we have such I/O in ZYNQ 7030 or 7045 that can receive ADC digital data with CML specification JESD204.

What is the intended bit rate?

Xilinx has an IP core to support JESD204 https://www.xilinx.com/products/technology/high-speed-serial/jesd204-high-speed-interface.html

You must have missed this when searching on Xilinx's site.

The FPGA needs to have serial transceivers available, i.e. GTP, GTX, and GTH.

Hi, I am planing to use ADS54J20 which is 12 bit dual 1000 MSPS. We need to use ZYNQ SOC for some reason. I have checked that XC7Z035 and XC7Z045 have 16 GTX. The ADC have 16 digital outputs but I am not sure if XC7Z035 and XC7Z045 can support/receive1000 MSPS from ADC.

Just another question for my understanding. If the FPGA/ZYNQ SOC have GTX, then do I still need to use the XIlinx LogiCORE™ IP JESD204 core ?
