HDMI PHY connection

Jump to solution

Hello,

 

I'm currently developing a custom board based on a Zynq Ultrascale+ IC and I need to have a HDMI transmitter available. I'm failing to understand if the having the following IP cores, HDMI Tx Subsystem + Video PHY Controller, is enough to connect a normal display to the the board. Or if an extra integrated circuit needs to be included on the PCB in order to have the IP cores working.

 

Thanks in advance,

Miguel Silva

Hi @miguelsilva5,

 

To implement the HDMI TX SubSystem + Video PHY:

 

If you plan on using multiple resolutions that require different clock speeds, you will need a programmable reference clock input.

Also, for compliance, Xilinx recommends adding a DP159 retimer chip.

 

For more information, please take a look at PG235, specifically pages 62-63 and UG1182 specifically pages 64-67.

 

 

PG235 shows a diagram of our FMC cards which include a retimer and clock generator. PG235 also has a section on Clocking that you may find helpful as well.

 

UG1182 shows our implementation of the HDMI TX and RX circuitry on our ZCU102 development board, including the HDMI Interface Circuit.
