Serial Audio Interface
The CS5342 supports both I²S and Left-Justified serial audio formats. Upon start-up, the CS5342 will detect
the logic level on SDOUT (pin 4). A 10 kΩ pull-up resistor to VL is needed to select I²S format, and a 10 kΩ
pull-down resistor to GND is needed to select Left-Justified format. Please see
more information on the required timing for the two serial audio interface formats.

Master Clock
The CS5342 requires a Master clock (MCLK) which runs the internal sampling circuits and digital filters.
There is also an internal MCLK divider which is automatically activated according to the frequency of the
MCLK.
common audio output sample rates and the required MCLK frequency. Please note that not all of the listed
sample rates are supported when operating with a fast MCLK (768x, 384x, 192x for Single-, Double-, and
Quad-Speed Modes, respectively).
