Hi Team,

Could you please tell me what the "HDMI Clock Rate" in the EyeScan Tool - Status tab shows ??

Is this actual TMDS Clock frequency ?

Is this the maximum TMDS clock which could be used for the SINK device ?

How is this value detected by TMDS181/171 ?

Best Regards,

Kawai,

This is the clock rate detected by the TMDS181/TMDS171 device on the reciever, it is an approximation.

Hi JMMN-san,

So I understood that this shows the "approximate input TMDS clock frequency" to the TMDS171/181.

Is this function still available when the device lock status is UNLOCKed ??

Hi Kawai,

The reported detected clock frequency is not valid if the clock is not locked. It may show the previously locked value.
