5. PIN DESCRIPTION

Pin Name # Pin Description

VD 4

Digital Power (Input) - Positive power supply for the digital section. Refer to the Recom-

mended Operating Conditions for appropriate voltages.

GND

Ground (Input) - Ground reference. Should be connected to analog ground.

MCLK 6

Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters. Table 5

illustrates several standard audio sample rates and the required master clock frequencies.

LRCK1

LRCK2

Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the

serial audio data line. The frequency of the left/right clock must be at the audio sample rate, Fs.

SDIN1

SDIN2

SDIN3

Serial Data Input (Input) - Input for two’s complement serial audio data.

SCLK1

SCLK2

Serial Clock (Input) - Serial clocks for the serial audio interface.

TST

Test - These pins need to be tied to analog ground.

RST 19

Reset (Input) - The device enters a low power mode and all internal registers are reset to their

default settings when low.

VA 32

Analog Power (Input) - Positive power supply for the analog section. Refer to the Recom-

mended Operating Conditions for appropriate voltages.

VLS 43

Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio

interface. Refer to the Recommended Operating Conditions for appropriate voltages.

VLC 18

Control Port Power (Input) - Determines the required signal level for the control port and

stand- alone configuration pins. Refer to the Recommended Operating Conditions for appropri-

ate voltages.
