Pin Name

I/O

Pin Function and Description

1SDATA

I

Serial Audio Data Input - Two’s complement MSB-first serial data is input on this pin. The data is

clocked into the CS4334/5/8/9 via internal or external SCLK, and the channel is determined by

LRCK.

2DEM/SCLK

I

De-Emphasis/External Serial Clock Input - Used for de-emphasis filter control or external serial

clock input.

3

LRCK

I

Left/Right Clock - Determines which channel is currently being input on the Audio Serial Data

Input pin, SDATA.

4MCLK

I

Master Clock - Frequency must be 256x, 384x, or 512x the input sample rate in BRM and either

128x or 192x the input sample rate in HRM.

5AOUTR

O

Analog Right Channel Output - Typically 3.5 Vp-p for a full-scale input signal.

6AGND

I

Analog Ground - Analog ground reference is 0V.

7VA

I

Analog Power - Analog power supply is nominally +5 V.

8AOUTL

O

Analog Left Channel Output - Typically 3.5 Vp-p for a full-scale input signal.
