No Connect -
These pins are not connected internally and should be tied to DGND to mini-
mize noise coupling.

2,3
Crystal Connections (Input/Output) -
Input and output connections for the crystal used to
clock the CS4220. Alternatively, a clock may be input into XTI. This is the clock source for the
delta-sigma modulator and digital filters. The frequency of this clock must be either 256x, 384x,
or 512x Fs in Slave Mode and 256x in Master Mode.
LRCK
4
Left/Right Clock (Input) -
Determines which channel is currently being input/output of the
serial audio data pins SDIN/SDOUT. The frequency of the Left/Right clock must be equal to the
input sample rate. Although the outputs for each ADC channel are transmitted at different
times, Left/Right pairs represent simultaneously sampled analog inputs. The required relation-
ship between the left/right clock, serial clock and serial data is defined by the DIF1-0 pins. The
options are detailed in Figures 8 - 11.
SCLK
5
Serial Data Clock (Input) -
Clocks the individual bits of the serial data into the SDIN pin and
out of the SDOUT pin. The required relationship between the left/right clock, serial clock and
serial data is defined by the DIF1-0 pins. The options are detailed in Figures 8 - 11.
VD
6
Digital Power (Input) -
Positive power supply for the digital section. Typically 5.0 VDC.
DGND
7
Digital Ground (Input) -
Digital ground for the digital section.
SDOUT
8
Serial Data Output (Output) -
Two’s complement MSB-first serial data is output on this pin.
The required relationship between the left/right clock, serial clock and serial data is defined by
the DIF1-0 pins. The options are detailed in Figures 8 - 11.
SDIN
9
Serial Data Input (Input) -
Two’s complement MSB-first serial data is input on this pin. The
required relationship between the left/right clock, serial clock and serial data is defined by the
DIF1-0 pins. The options are detailed in Figures 8 - 11.
