This is a high–impedance input. Voicefrequency signals
present on this input are encoded as an A–law or
μ

PCM bit stream and shifted out on the selected D

Transmit Data
D

1 is available on theTS5070 only, D
X
0 is available on
all devices. These transmit data TRI–STATE
outputs
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.

0 is available on all devices. Normally these opendrain
outputs are floating in a high impedance state except
when a time–slotis activeon one of the D
X
outputs, when
the apppropriate TS

output pulls low to
enable a backplane line–driver. Should be strapped to
ground (GND) when not used.

Receive Analog
The receive analog power amplifier output, capable of
driving load impedances as low as 300
(depending on
the peak overload levelrequired). PCM datareceived on
the assigned D

pin is decoded and appears at this output
as voice frequency signals.
