SN65DP149: SN65DP149 Re-Driver/Re-timer closing the eye of the signal

Part Number: SN65DP149


We are noticing that the signal coming out of the SN65DP149RSBT is adding significant jitter to the HDMI signal. Below is the input of the IC at pin 6 and 7 ( IN_D0x)

Below is the output of the IC on pin 24 and 25 (OUT_D0)

We have tried settings like slew rate, pre-empasis, de-emphasis and equalization. There is no significant change in signal quality.

Any ideas what is causing it? Any TI folks who comment on this signal issue? We have tried multiple boards with no differences in signal quality.
