PIN DESCRIPTIONS
No. Pin Name I/O Pin Function and Description
1SDATAI
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.
4MCLKI
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.
5AOUTROAnalog Right Channel Output - Typically 3.5 Vp-p for a full-scale input signal.
6AGNDIAnalog Ground - Analog ground reference is 0V.
7VAIAnalog Power - Analog power supply is nominally +5 V.
8AOUTLOAnalog Left Channel Output - Typically 3.5 Vp-p for a full-scale input signal.
