ADV7180 - How to communicate over I2C

Our customer is asking about how to communicate with this device over I2C. Questions are like this:

 

All I need to access this part thru I2C bus is power and ground to the part, the ALSB hi or low for the address (we have it pulled down) and I would guess nothing else (not even the clock running)?

Maybe we need to wait a certain amount of clock between addressing the part and reading back, etc….I just want the minimum stuff attached to get the I2C bus reading from the part….

 

What needs to be connected to the ADV7180 inorder to do I2C communication?  Obviously, power, ground, SDA and SCL...but are there any other connections needed?  Like a System Clock?

 

Thank you. -DN
