SYSTEM DESCRIPTION
Receive Path Configurations
In the receive signal path (see
Figure 1
), the internal
equalizer can be included by setting REQB = 0 or
bypassed by setting REQB = 1. The equalizer bypass
option allows easy interfacing of the XRT7295AT device
into systems already containing external equalizers.
Figure 3
illustrates the receive path options.
In Case 1 of
Figure 3
, the signal from the DSX-3
cross-connect feeds directly into R
IN
. In this mode, the
user should set REQB = 0, engaging the equalizer in the
data path.
In Case 2 of
Figure 3
, external line build-out (LBO) and
equalizer networks precede the XRT7295AT device. In
this mode, the signal at R
IN
is already equalized, and the
on-chip filters should be bypassed by setting REQB=1.
In applications where the XRT7295AT device is used to
monitor DS3 transmitter
outputs directly, the receive
equalizer should be bypassed.
Maximum input amplitude under all conditions is 850mV
pk.
