R
Receive data input. PCM data is shifted
into D
R
following the FS
R
leading edge.
BCLK
R
/CLKSEL The bit clock which shifts data into D
R
af-
ter the FS
R
leading edge. May vary from
64 kHz to 2.048 MHz. Alternatively, may
be a logic input which selects either
1.536 MHz/1.544 MHz or 2.048 MHz for
master clock in synchronous mode and
BCLK
X
is used for both transmit and re-
ceive directions (see Table I).

should be synchronous with MCLK
X
for best per-
formance. When MCLK
R
is connected continu-
ously low, MCLK
X
is selected for all internal tim-
ing. When MCLK
R
is connected continuously
high, the device is powered down.
MCLK
X
Transmit master clock. Must be 1.536 MHz,
1.544 MHz or 2.048 MHz. May be asynchronous
with MCLK
R
. Best performance is realized from
synchronous operation.
FS

Transmit frame sync pulse input which enables
BCLK
X
to shift out the PCM data on D
X
. FS
X
is
an 8 kHz pulse train, see Figures 2 and 3 for
timing details.
BCLK

The bit clock which shifts out the PCM data on
D
