[HDMI TX ip] Can I generate TMDS clock +0.5% and TMDS clock -0.5%

Jump to solution

Hi,

For one of source HDMI CTS test, the two different frequencies are the minimum and maximum permitted by a source. 

For example: 1920x1080@60Hz (TMDS clock is 148.5 MHz), these value are 1920x1080@59.64Hz (TMDS clock is 147.609 MHz)and 1920x1080@60.3Hz (TMDS clock is 149.2425 MHz)

Is it possible to generate maximum tmds clock and minimum tmds clock with HDMI TX ip?

 

Thanks

Sitting

Hi @sitting

 

 

 

Yes.

It depends on input clock of HDMI Tx IP.
