Hi Jay,

  • Worst case is you can consider to purchase Bitec daughter card rev 11 to help improve the signal integrity

Thanks.

    Hi Dlim,

    Do you know why Bitec replaced Pericom re-drivers with TI re-driver and re-timer on its HDMI 2.0 daughter card?

    Does the TI chips provide better noise/jitter resistance (or other benefits in terms of signal quality) than the Pericom counterparts? Or is it just some logistic consideration (e.g. cost)?

    Thanks,

    Jay
