Function
Normally a pulse or squarewave waveform with an 8 kHz
repetition rate is applied to this input to define the start of
the transmit time-slot assigned to this device (non-delayed
data mode) or the start of the transmit frame (delayed
data mode using the internal time-slot assignment
counter).
This is a high–impedance input. Voice frequency signals
present on this input are encoded as an A–law or –law
PCM bit stream and shifted out on the selected D

remain in the high impedance state except during the
assigned transmit time–slot on the assigned port, during
which the transmit PCM data byte is shifted out on the
rising edges of BCLK.
