PRIMARY AUDIO INTERFACE TRANSMITTER (PAIF TX)

The PAIF Transmitter requires a left-right-clock (LRCLK) and a bit-clock (BCLK). These can be

supplied externally (slave mode) or they can be generated internally by the WM8580 (master mode).

The master mode LRCLK/BCLK are created by the Master Mode Clock Generator module. The

control of this module is described on page 21.

The clock supplied to this module can be ADCMCLK, PLLACLK, PLLBCLK, or MCLK and is selected

by the internal signal paiftxms_clksel’. If the PAIF Transmitter is sourcing the S/PDIF Receiver, it is

recommended that the interface operate in master mode. For this path, paiftxms_clksel selects

PLLACLK. For all other digital routing options, paiftxms_clksel selects whichever clock the adc_clk is

using.

If in slave mode, and adc_clk is set to be MCLK, then the PAIFRX_BCLK is used as the BCLK for

the PAIF Transmitter.
