CS4384
4. APPLICATIONS
The CS4384 serially accepts twos complement formatted PCM data at standard audio sample rates including 48,
44.1 and 32 kHz in SSM, 96, 88.2 and 64 kHz in DSM, and 192, 176.4 and 128 kHz in QSM. Audio data is input via
the serial data input pins (SDINx). The Left/Right Clock (LRCK) determines which channel is currently being input
on SDINx, and the Serial Clock (SCLK) clocks audio data into the input data buffer. For more information on serial
audio interfaces see AN282 “The 2-Channel Serial Audio Interface: A Tutorial”.
The CS4384 can be configured in Hardware Mode by the M0, M1, M2, M3 and M4 pins and in Software Mode
through IC or SPI.

Master Clock
frequency at which words for each channel are input to the device. The MCLK-to-LRCK frequency ratio and
speed mode is detected automatically during the initialization sequence by counting the number of MCLK
transitions during a single LRCK period and by detecting the absolute speed of MCLK. Internal dividers are
then set to generate the proper internal clocks. Tables 1 - 3 illustrate several standard audio sample rates
and the required MCLK and LRCK frequencies. Please note there is no required phase relationship, but
MCLK, LRCK and SCLK must be synchronous.
