4.0 APPLICATIONS
4.1
The output sample rate, Fs, can be adjusted from 2 kHz to 204 kHz. The CS5361 must be set to the proper speed
mode via the mode pins, M1 and M0. Refer to Table 1.
4.2
The device supports operation in either Master Mode, where the left/right and serial clocks are synchronously gen-
erated on-chip, or Slave Mode, which requires external generation of the left/right and serial clocks. The device also
includes a master clock divider in Master Mode where the master clock will be internally divided prior to any other
internal circuitry when MDIV is enabled, set to logic 1. In Slave Mode, the MDIV pin needs to be disabled, set to logic
0.
4.2.1
LRCK and SCLK operate as inputs in Slave mode. The left/right clock must be synchronously derived from the mas-
ter clock and be equal to Fs. It is also recommended that the serial clock be synchronously derived from the master
clock and be equal to 64x Fs to maximize system performance. Refer to Table 2 for required clock ratios.
