„ System Clock
mode. And these are XTI, LRCK(fs) and BCLK at
slave mode. In case of using slave mode, XTI and
LRCK must be synchronized but those phases do not
need to be muched.
Master clock can be obtained by quartz oscillator
connected between XTI pin and XTO pin, or by
openning XTO pin and inputting the external
clock to XTI pin.
The frequencies of each clocks needed for standard
audio rate is shown in the table below.
