WM8772EDS – 28 LEAD SSOP

Production Data

PD Rev 4.2 October 2005

DSP MODE A

In DSP mode A, the MSB of DAC channel 1 left data is sampled by the WM8772EDS on the second

rising edge on BCLK following a LRC rising edge. DAC channel 1 right and DAC channels 2 and 3

data follow DAC channel 1 left data (Figure 26).

The MSB of the left channel ADC data is output on DOUT and changes on the first falling edge of

BCLK following a low to high LRC transition and may be sampled on the rising edge of BCLK. The

right channel ADC data is contiguous with the left channel data (Figure 26)
