4. APPLICATIONS
4.1
Single-, Double-, and Quad-Speed Modes
The CS5340 can support output sample rates from 2 kHz to 200 kHz. The proper speed mode can be de-
termined by the desired output sample rate and the external MCLK/LRCK ratio, as shown in Table 1.
Table 1. Speed Modes and the Associated Output Sample Rates (Fs)
4.2
Operation as Either a Clock Master or Slave
The CS5340 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.
