Word clock 2 input
terminal: internal
signal to latch digital
audio data {CH1 data)
is generated by using
fall of WCLK2 when
IF is in Jow ijevel.
LR elock 2 input
terminal: CH1 and
CH2 of input digital
audio data are
indicated.
Word clock 1 input
terminal: internal
signal to latch the
digital audio data (CH2
data) is generated by
using fall of WCLK1
when IF is in low level.
