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 f
S
or 48 f
S
. 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 f
S
. 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
