Pin Function and Description

1

SDATA

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

The data is clocked into the CS4334/5/6/7/8/9 via internal or external SCLK, and the

channel is determined by LRCK.

2 DEM/SCLK I De-Emphasis/External Serial Clock Input - used for de-emphasis filter control or exter-

nal serial clock input.

3

LRCK

I Left/Right Clock - determines which channel is currently being input on the Audio Serial

Data Input pin, SDATA.

4

MCLK

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.

5 AOUTR O Analog Right Channel Output - typically 3.5 Vp-p for a full-scale input signal.

6

AGND

I Analog Ground - analog ground reference is 0V.

7

VA

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

8 AOUTL O Analog Left Channel Output - typically 3.5 Vp-p for a full-scale input signal.
