4 APPLICATIONS

4.1 Single, Double, and Quad Speed Modes

The CS5342 can support output sample rates from 2 kHz to 200 kHz. The proper speed mode can be determined

by the desired output sample rate and the external MCLK/LRCK ratio, as shown in Table 1.

4.2 Operation as Either a Clock Master or Slave

The CS5342 supports operation as either a clock master or slave. As a clock master, the LRCK and SCLK pins are

outputs with the left/right and serial clocks synchronously generated on-chip. As a clock slave, the LRCK and SCLK

pins are inputs and require the left/right and serial clocks to be externally generated. The selection of clock master

or slave is made via the Mode pins as shown in Table 2.
