ADV7842 External Memory Controller

Dear,

 

In our design we are not interested by features bring by an external memory on ADV7842. In UG-214 it is said that we must tied to GND the DQS pins of the memory controller when unused.

With a BGA chip it is more convenient to connect a ball directly to GND and not through a resistor. So is it really needed to tied them to GND or could we connect them to GND or maybe left them unconnected ? Thank you in advance.

 

Yannick
