DESCRIPTION
The 78P7200 is a line interface transceiver IC
intended for STS-1 (51.84 Mbit/s), DS3 (44.736
Mbit/s) and E3 (34.368 Mbit/s) applications. The
receiver has a very wide dynamic range and is
designed to accept either HDB3 or B3ZS-encoded
Alternate-Mark Inversion (AMI) inputs; it provides
CMOS logic level clock, positive data, negative data
and low-level signal detector outputs. An on-chip
equalizer improves the intersymbol interference
tolerance on the receive path. The transmitter
converts CMOS logic level clock, positive data and
negative data input signals into AMI pulses of the
appropriate shape for transmission. A line buildout
(LBO) equalizer may be selected to shape the
outgoing pulses for shorter line lengths. The
78P7200 requires a single 5 volt supply and is
available in a surface mount package.
