Later, I redesigned my system and upgraded to the ADIS16209.
Will ADIS16209 work even if pin 8 and 10 is connected to ground or do we need
to modify the pcb?
The ADIS16201 and ADIS16209 are identical with respect to these pins.
The ADIS16209 will function exactly the same as the ADIS16201 with pins 8 and
10 connected to ground.
