SYSTEM DESCRIPTION
XR–T3588
The function of the transmitter is to take a TTL input signal
at a maximum bit rate of 1OMbps and output a balanced
differential signal with a peak amplitude of 0.55V and a
maximum DC offset of 0.6V. An internal buffer provides
the regulated output voltage to set the mean level of the
transmitters to less than 0.6V.
Figure 5 shows a simplified
circuit for the output stage.
To meet the pulse shape and offset requirements laid
down in the V.35 specification, the transmitter employs an
internal temperature compensated voltage generator to
provide reference voltages for both offset control and
output current generation. Load resistors for the output
stage, which provide the required source impedance for
the transmitter, are external to the IC and are required to
meet the V.35 specified tolerance.
XR–T3589
The XR-T3589 Line Receiver contains three identical
receive circuits to complement the XR-T3588 Line
Transmitter. Received differential signals are converted
into a single TTL compatible output. The input stage is
designed to meet the full V.35 noise and common mode
input specification.
Individual receivers may be shut down to achieve power
savings for applications not requiring three channels. Two
TTL compatible inputs provide four combinations of
transmitter configurations, as defined in table 2. If either of
the select pins is left open a high state is adopted, hence
with no inputs applied, all channels are powered up.
However it is recommended to tie all select inputs to either
GND or VCC.
