Hi Gareth,
Do you wish to combine two SDI inputs into HDMI/DP?

Hi Gareth,

Our TDP portfolio may be able to combine the SDI inputs to output HDMI/DP. You will have to turn off DDC buffer and pull up HPD signal to ensure your data signals will be driven properly.

However, please note that this part will not re-encode your signal from NRZI to other protocols used on HDMI/DP and will have to be tested to ensure its functionality.

Best,
J
