Speed Modes
In TDM Mode, all eight channels of audio data are serially clocked out during a single Frame Sync (FS)
cycle, as shown in
channel slot occupies 32 SCLK cycles, with the data left justified and with MSB first. TDM output data
should be latched on the rising edge of SCLK within time specified under
ing” section on page
complimentary TDM data. All SDOUT pins will remain active during TDM Mode. Refer to
timizing Performance in TDM Mode” on page 29
The serial audio interface format of the data is controlled by the configuration of the DIF1 and DIF0 pins in
Stand-Alone Mode or by the DIF[1] and DIF[0] bits in the Global Mode Control Register in Control Port
Mode, as shown in
CS5368 supports sampling rates from 2 kHz to 21 kHz, divided into three ranges: 2 kHz - 54 kHz, 54 kHz -
108 kHz, and 108 kHz - 216 kHz. These sampling speed modes are called Single-Speed Mode (SSM),
Double-Speed Mode (DSM), and Quad-Speed Mode (QSM), respectively.
The Master/Slave operation and the sample rate range are controlled through the settings of the M1 and
M0 pins in Stand-Alone Mode, or by the M[1] and M[0] bits in the Global Mode Control Register in Control
Port Mode, as shown in
