TAS5026A
2.1.6 DCLK
DCLK is the internal high frequency clock that is produced by the PLL circuitry from MCLK. The TAS5026A
uses the DCLK to control all internal operations. DCLK is 8 times the speed of MCLK in normal speed mode,
4 times MCLK in double speed, and 2 times MCLK in quad speed. With respect to the I2C addressable
registers, DCLK clock cycles are used to specify interchannel delay and to detect when the MCLK frequency
is drifting. Table 24 DCLK shows the relationship between Sample Rate, MCLK, and DCLK.

2.1.7 Serial Data Interface
The TAS5026A operates as a slave only/receive only serial data interface in all modes. The TAS5026A has
three PCM serial data interfaces to accept six channels of digital data though the SDIN1, SDIN2, SDIN3 inputs.
The serial audio data is in MSB first; 2s complement format.
The serial data interfaces of the TAS5026A can be configured in right justified, I2S, left-justified, or DSP modes.
This interface supports 32-kHz, 44.1-kHz, 48-kHz, 88-kHz, 96-kHz, 176.4-kHz, and 192-kHz data sample
rates. The serial data interface format is specified using the data interface control register. The supported word
lengths are shown in Table 25.
During normal operating conditions if the serial data interface settings change state, an error recovery
sequence is initiated.
