How to connect ADV8005 PIN N23/W23

Hi

Base on  ADV8005_PRA, N23/W23 should connect to 1.8V,

But from the reference design(SCH and PCB),these two Pins no connection.

How to connect these two Pins?

 

On my board, I connect these 2 pins to 1.8v

Now I meet a issue,  TX 4K output not worked (TX Pll not locked, even for PVSP 4K freerun),  but 4K input works well (for example 4K to 1080P)

I already checked and improve the power ripple

I wonder if the issue related with these 2 pins connection

 

Thanks

 

Tommy
