SERIAL AUDIO DATA INTERFACE
The PCM1807 interfaces the audio system through LRCK (pin 7), BCK (pin 8), and DOUT (pin 9).

PCM1807
SLES147–SEPTEMBER 2005
The PCM1807 supports master mode and slave mode as interface modes, which are selected by MD1 and MD0.
MD1 and MD0 are controlled through the serial control port as shown in
Table 2
.
In master mode, the PCM1807 provides the timing of serial audio data communications between the PCM1807
and the digital audio processor or external circuit. While in slave mode, the PCM1807 receives the timing for data
transfer from an external controller.

Master mode
In master mode, BCK and LRCK work as output pins, and these pins are controlled by timing which is generated
in the clock circuit of the PCM1807. The frequency of BCK is fixed at 64 BCK/frame.
Slave mode
In slave mode, BCK and LRCK work as input pins. The PCM1807 accepts 64 BCK/frame or 48 BCK/frame
format (only for a 384 f
S
system clock), not 32 BCK/frame format.
The PCM1807 supports two audio data formats in both master and slave modes. The data formats are selected
by FMT, which is controlled through the serial control port as shown in
Table 3
.
Figure 21

formats in slave mode and master mode.
