Description
VDDIO
6, 34
PWR
Digital Supply Connections
A split power plane with analog and digital power is recommended for the
CS4103. A single delineation divides the analog and digital pins of the
device. The power planes should be placed on either side of this delineation
beneath corresponding analog and digital pins of the CS4103.
VSSIO
16, 28
GND
Digital Ground Connections
A split ground plane with analog and digital grounds is recommended for the
CS4103. A single delineation divides the analog and digital pins of the
device. The ground planes should be placed on either side of this delineation
beneath corresponding analog and digital pins of the CS4103.
