Is it possible for HDMI and PCIE to share single gtp quad(artix 7a50)?

Hi, 

 Is there a possibility of  PCIE(integerated) and HDMI sharing same gtp quad?

HDMI requires 3 gtp channel for data + tmds clk .  

 

Thank-You in advance.

Hey @yogesh_tripathi,

 

There is always a possibility ...

 

As you already stated, HDMI will require at least three of the four tranceiver which leaves you with a single tranceiver for PCIe. So far so good, but you need to address the HDMI clock (you can probably use a normal I/O for that) and utilize both MGT clocks in the quad with different settings for HDMI and PCIe. I'm pretty sure there is no reference design or official support for this though.

 

Hope this helps,

Herbert

Hi Herbert,

 

Thank-you for the quick reply.

Hope it works. One more doubt, Why GT wizard is showing only using one gtp_channel as shown in image below instead of three.

I'd say because you are only configuring one of the three (or four) channels ...

 

Best,
