Hi

ADV748x Evaluation board doen't have external pull up register on HPD/CBUS pin,

but Former HDMI Rx(suc as ADV7611/7612) has 1k pull up(to 5V) register on HPA pin

which pin has similar function as HPD/CBUS of ADV748x.

 

Would you let me the reason why ADV748x doesn't require pull up on HPD/CBUS pin?

 

Regards,

Tomoto
