CS4364

5.3.2

Functional Mode (FM)

Default = 11

00 - Single-Speed Mode (4 to 50 kHz sample rates)

01 - Double-Speed Mode (50 to 100 kHz sample rates)

10 - Quad-Speed Mode (100 to 200 kHz sample rates)

11 - Auto Speed Mode detect (32 kHz to 200 kHz sample rates)

Function:

Selects the required range of input sample rates or Auto Speed Mode.

5.4

DSD Control (address 04h)

5.4.1

DSD Mode Digital Interface Format (DSD_DIF)

Default = 000 - Format 0 (64x oversampled DSD data with a 4x MCLK to DSD data rate)

Function:

The relationship between the oversampling ratio of the DSD audio data and the required Master clock to

DSD data rate is defined by the Digital Interface Format pins.

The DSD/PCM bit determines whether PCM or DSD mode is selected.
