Hi !

 

I have a question about ADV748x.

At the EVAL-Board, there is no ESD device at RX_5V_VBUS line.

 

When the device's power supply is OFF and HDMI is connected ,

5V will input to RX_5V_VBUS line.

 

At the datasheet it looks OK to input 5V to RX_5V_VBUS line even when the power supply off.

Is my understanding correct?

Is there some circuit at RX_5V_VBUS pin to protect latch-up or something?

 

Best regards.

Kawa
