Hi
I made a custom board that contain the ADV7280.
The design of the ADV7280 was done according to the EVM sch and pcb, followed by
All the pdf files I could find.
Running the board I checked the power up sequence, voltage level, reset/power
down pins, etc.
All the parameter are good and match the pdf files.
The only problem is that the device is not answering on the I2C bus.
I tried every possible slave address, clock speed (25KHz – 400KHz), but nothing
works.
Next I checked the pcb design, source of the devices (DigiKey), assembly, but
nothing there.
Is there something else I should be checking before I give up and change my
design.
