Master Clock
The CS5341 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 based on the speed mode and
frequency of the MCLK. Table 3 shows a listing of the external MCLK/LRCK ratios that are required.
Table 4 lists some 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 (512x, 256x, 128x
for Single-, Double-, and Quad-Speed Modes, respectively).

Serial Audio Interface
The CS5341 supports both IS and Left-Justified serial audio formats. Upon start-up, the CS5341 will detect
the logic level on SDOUT (pin 4). A 10 k
pull-up to VL is needed to select IS format, and a 10 k pull-
down to GND is needed to select Left-Justified format. Figures 19 and 20 illustrate the IS and Left-Justified
audio formats. Please see Figures 13 through 16, for more information on the required timing for the two
serial audio interface formats. Also see Application Note AN282 for a detailed discussion of the serial audio
interface formats.
