Power Supply Connections

VD+ - Positive Digital Power, PIN 7.

Positive supply for the digital section. Nominally +5 volts.

VA+ - Positive Analog Power, PIN 22.

Positive supply for the analog section. Nominally +5 volts. This supply should be as quiet as

possible since noise on this pin will directly affect the jitter performance of the recovered

clock.

DGND - Digital Ground, PIN 8.

Ground for the digital section. DGND should be connected to same ground as AGND.

AGND - Analog Ground, PIN 21.

Ground for the analog section. AGND should be connected to same ground as DGND.

Audio Output Interface

SCK - Serial Clock, PIN 12.

Serial clock for SDATA pin which can be configured (via control register 2) as an input or

output, and can sample data on the rising or falling edge. As an input, SCK must contain 32

clocks for every audio sample in all normal audio serial port formats.
