FSR
Receive frame sync pulse which enables
BCLKR to shift PCM data into DR FSR is
an 8 kHz pulse train See
Figures 2 and 3
for timing details
DR
Receive data input PCM data is shifted
into DR following the FSR leading edge
BCLKR CLKSEL The bit clock which shifts data into DR af-
ter the FSR leading edge May vary from
64 kHz to 2048 MHz Alternatively may
be a logic input which selects either
1536 MHz1544 MHz or 2048 MHz for
master clock in synchronous mode and
BCLKX is used for both transmit and re-
ceive directions (see Table I)

should be synchronous with MCLKX for best per-
formance When MCLKR is connected continu-
ously low MCLKX is selected for all internal tim-
ing When MCLKR is connected continuously
high the device is powered down
MCLKX
Transmit master clock Must be 1536 MHz
1544 MHz or 2048 MHz May be asynchronous
with MCLKR Best performance is realized from
synchronous operation
FSX
Transmit frame sync pulse input which enables
BCLKX to shift out the PCM data on DX FSX is
an 8 kHz pulse train see
Figures 2 and 3 for
timing details
BCLKX
The bit clock which shifts out the PCM data on
DX May vary from 64 kHz to 2048 MHz but
must be synchronous with MCLKX

PCM data output which is en-
abled by FSX
TSX
Open drain output which pulses low during the
encoder time slot
GSX
Analog output of the transmit input amplifier
Used to externally set gain
