PCM3060

SLAS533 – MARCH 2007

The digital audio data can be interfaced in either slave or master mode, and this interface mode is selectable

using the serial mode control described in the Mode Control section.

The interface mode is also selectable independently for the ADC and the DAC. DIN is always input to the

PCM3060 and DOUT is always an output from the PCM3060. Slave mode is the default mode for both the ADC

and the DAC.

In slave mode, BCK1/2 and LRCK1/2 are inputs to the PCM3060, and BCK1/2 must be either 64 fS or 48 fS. DIN

is sampled on the rising edge of BCK2, and DOUT is changed on the falling edge of BCK1. The default timing

specification is shown in Figure 24.

In master mode, BCK1/2 and LRCK1/2 are outputs from the PCM3060. BCK1/2 and LRCK1/2 are generated by

the PCM3060 from SCKI1/2, and BCK1/2 is fixed at 64 fS. DIN is sampled on the rising edge of BCK2, and

DOUT is changed on the falling edge of BCK1. The detailed timing specification is shown in Figure 25.
