Operation as Clock Master or Slave
The CS5343/4 supports operation as either a clock master or slave. As a clock master, the left/right and
serial clocks are synchronously generated on-chip and output on the LRCK and SCLK pins, respectively.
As a clock slave, the LRCK and SCLK pins are always inputs and require external generation of the left/right
and serial clocks. The selection of clock master or slave is made via a 10 kΩ pull-up resistor from SDOUT
to VA for Master Mode selection or via a 10 kΩ pull-down resistor from SDOUT to GND for Slave Mode se-
lection, as shown in
Slave Mode Operation
A unique feature of the CS5343/4 is the automatic selection of either Single- or Double-Speed Mode when
acting as a clock slave. The auto-mode selection feature supports all standard audio sample rates from
4 to 108 kHz. Please refer to
