Hi,
I will be glad to get some explanation about groud separation in PCBs,
I am looking at the design of the SparkFun PCM1803A (https://www.sparkfun.com/products/retired/9365)
and I see that in the schematic and in the PCB design, there are two grounds, Digital and Analog,
But there is only one source (+5v and GND) for the board, so how can it be?
why the grounds are separated on board and there is some small net bellow the PCM1803 chip that crosses the two grounds together?
Thanks a lot!
best,
Alon
