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.
De-Emphasis/External Serial Clock Input - used for de-emphasis filter control or exter-
nal serial clock input.
Left/Right Clock - determines which channel is currently being input on the Audio Serial
Data Input pin, SDATA.
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.
Analog Ground - analog ground reference is 0V.
Analog Power - analog power supply is nominally +5V.
