Are there PCB Layout Design Guidelines for UCD8248 regarding AGND and DGND?

What is recommended, using 2 separate GND's or connect both AGND and DGND pins to one GND?

Regards Mat.

HI Mawu,

You can separate AGND and DGND for UCD9248, then connect both AGND and DGND to board power ground.

Thanks

Hi Qian thanks,

I have seen both solutions - using only one GND plane (AGND & DGND pins connected together) - and AGND pins and DGND pins using 2 separate GND planes which are connected together at a certain point.

What is recommended by TI?

Regards Mat.

Hi Mawu,

It is suggested to use two separate ground planes for AGND and DGND.

Thanks
