Hi!

 

I have a question about ADV7281A.

At the datasheet, it tell us how to power up ADV7281A.

Our customer want to turn on 3.3V and 1.8V supply within 100 μs.

It is very important to keep 3.3V > 1.8V.

(ADV728x)POWER-UP SEQUENCE of ADV728x 

But there is no specification for raising time.

Is 100us OK to power up?

Do you have any specification for raising time?

 

They will made their prototype PCB very soon so if you can answer to my question, it will help us.

 

Best regards

Kawa
