the PLLs, internal logic, and IO pins. The PLLs and internal logic use 1.8 V supply voltage. The IO pins use
3.3 V supply voltage. An optional separate supply can be used to provide clean 3.3 V to the Sigma-Delta
DACs digital output pads. It is recommended that you use good layout techniques to provide isolation be-
tween the supply types on the board. Contact Cirrus Logic applications engineering for layout guidelines.
