Oversampling Modes
The CS4364 operates in one of three oversampling modes based on the input sample rate. Mode selection
is determined by the M4, M3 and M2 pins in Hardware Mode or the FM bits in Software Mode. Single-Speed
Mode supports input sample rates up to 50 kHz and uses a 128x oversampling ratio. Double-Speed Mode
supports input sample rates up to 100 kHz and uses an oversampling ratio of 64x. Quad-Speed Mode sup-
ports input sample rates up to 200 kHz and uses an oversampling ratio of 32x.
The auto speed-mode detect feature allows for the automatic selection of speed mode based off of the in-
coming sample rate. This allows the CS4364 to accept a wide range of sample rates with no external inter-
vention necessary. The auto speed-mode detect feature is available in both Hardware and Software Mode.
OLM #1
OLM #1 serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave to
SCLK at 128 Fs. Six channels of MSB first 20-bit PCM data are input on SDIN1.
OLM #2
OLM #2 serial audio interface format operates in Single-, Double-, or Quad-Speed Mode and will slave to
SCLK at 256 Fs. Six channels of MSB first 24-bit PCM data are input on SDIN1.
