1080p limitations in Zybo Z7-020

[Gaurav Agrawal]

For Zybo Z7-20, the HDMI input/output demo says that 1080p (1920×1080@60Hz) is not fully supported. Please let me know the features that are not supported for 1080p, and what is the reason for non-support.

Regards

Gaurav

HI @Gaurav Agrawal,

I have reached out to get a more specific answer to your question.

Thanks,

Artix-7 (and thus Zynq-7000) clocking architecture and speed grade does not support 148.5 MHz x 5 = 742.5 MHz BUFIO clock. Therefore, 1080p is overclocking the FPGA. Although it is expected to work at room temperature it is possible that it won't work over the whole temperature range and across silicon.
