TUSB1064: HDMI issue

Part Number: TUSB1064

600Hi,

I have meet HDMI can't work issue, the problem is plug in HDMI cable but no feedback.

And we capture the SBU1/SBU2/AUXp/AUXn signal seems strange. please refer to below.

AUXn is different with SBU1, is may caused by layout? 

Please provide me your e-mail address I will send schematic and layout to you for reference.

CH1: SBU1 CH2: AUXn

CH1: SBU2 CH2: AUXp

Thanks!

Jeff

    Would you please accept my friendship request and you can then send me the schematic and layout in a private message?

    Below is the TUSB1064 AUX/SBU common mode voltage requirement. The common mode voltage is set by the external pullup/pulldown resistor.

    Since the output of the TUSB1064 is DP, please make sure you are using an active DP to HDMI protocol converter, not the passive level shifter when connecting to a HDMI monitor.

    Thanks
