GENERAL DESCRIPTION
The XRT5894 is an optimized four channel 3.3V line
interface unit fabricated using low power CMOS
technology. The device contains four independent E1
channels. Each channel performs the driver and receiver
functions necessary to convert bipolar signals to logical
levels and vice versa. The device requires transformers
on both receiver and transmitter sides, and supports both
balanced and unbalanced interfaces.
The device offers two distinct modes of LOS detection.
The first method, which does not require an external
clock, provides an LOS output indication signal with
thresholds and delay that comply with the ITU G.775
requirements. In the second mode, the user provides an
external clock that increases the delay for LOS
declaration and clearing. This feature provides the user
with the flexibility to implement LOS specifications that
require a delay greater than the G.775 requirements.
