Operational Mode/Sample Rate Range Select
The output sample rate, Fs, can be adjusted from 2 kHz to 204 kHz. The CS5351 must be set to the proper
speed mode via the mode pins, M1 and M0. Refer to
System Clocking
The device supports operation in either Master Mode, where the left/right and serial clocks are synchronous-
ly generated 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.

Slave Mode
LRCK and SCLK operate as inputs in Slave Mode. The left/right clock must be synchronously derived
from the master 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
for required clock ratios.
