Hi !

 

I have few question about ADV7390

(1)

At the datesheet , W grade support 105deg.

But the specification is 85deg max.

Does this device can support 105deg by W grade?

And if it can , is the specification value are everything same?

2)

At the datasheet , Iin = 10uA max @ 3.3V.

When the VDD = 1.8V , are the value same?

3)

At EVAL-board circuit, 33r is used at input pin.

I think the input leakage is 10uA max so it doesn't care the value so much but our customer are trying to use 22r.

I think it would be OK but if is there anything to take care , can you give me some advise?

As for the sink ability of the buffer of the device of the counterpart, what mA will be assumed?

If the device which input signal to ADV7390 has more than 10uA , would it OK?

They want to know why eval board use 33r.

 

Best regards.
