At DesignCon 2019, Xilinx and Molex show a pair of demonstrations. First, the Xilinx GTM 58G PAM4 SERDES found in Virtex UltraScale+ FPGAs operates over 3m of QSFP-DD Direct Attach Copper, facilitated by Molex Near-Stack high speed connectivity solutions. Next, the Xilinx 112G PAM4 test device operates over an evaluation Molex Impulse Orthogonal backplane, showing next generation interconnect today.
