Hi team,
The customer is using DDC2256A along with Xilinx Artix 7 FPGA. The datasheet shows the min VIH is 0.8DVDD and the max VOL is 0.2DVDD. That is if DVDD is
1.8V, the min VIH is 1.44V and the max VOL is 0.36V. But FPGA cannot meet these two values.
Q1: Is there any ways to solve this issue?
Q2: The datasheet also shows the differential output voltage(VOD) is 700mVpp. But the maximum differential input for Artix 7 FPGA is 600mV.
Is there any ways to solve this issue?
Best Wishes,
