XRT83SH38

8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
REV. 1.0.7
FUNCTIONAL DESCRIPTION
The XRT83SH38 is a fully integrated 8-channel short-haul line interface unit (LIU) that operates from a single
3.3V power supply. Using internal termination, the LIU provides one bill of materials to operate in T1, E1, or J1
mode with minimum external components.
The LIU features are programmed through a standard
microprocessor interface or controlled through Hardware mode. EXAR’s LIU has patented high impedance
circuits that allow the transmitter outputs and receiver inputs to be high impedance when experiencing a power
failure or when the LIU is powered off. Key design features within the LIU optimize 1:1 or 1+1 redundancy and
non-intrusive monitoring applications to ensure reliability without using relays. The on-chip clock synthesizer
generates T1/E1/J1 clock rates from a selectable external clock frequency and outputs a clock reference of the
line rate chosen. Additional features include RLOS, a 16-bit LCV counter for each channel, AIS, QRSS
generation/detection, Network Loop Code generation/detection, TAOS, DMO, and diagnostic loopback modes.
1.0 HARDWARE MODE VS HOST MODE
The LIU supports a parallel or (serial) microprocessor interface (Host mode) for programming the internal
features, or a Hardware mode that can be used to configure the device.
1.1
Feature Differences in Hardware Mode
Some features within the Hardware mode are not supported on a per channel basis. The differences between
Hardware mode and Host mode are descibed below in Table 1.

HARDWARE MODE
Tx Test Patterns
Fully Supported
QRSS diagnostic patterns are not available in Hardware mode.
The TAOS feature is available.
RxRES[1:0]
Per Channel
In Hardware mode, RxRES[1:0] is a global setting that applies to
all channels.
TERSEL[1:0]
Per Channel
In Hardware mode, TERSEL[1:0] is a global setting that applies to
all channels.
EQC[4:0]
Per Channel
In Hardware mode, the EQC[4:0] is a global setting that applies to
all channels.
NOTE: In Host mode, all channels have to operate at one line rate
T1 or E1, however each channel can have an individual
line build out.
Dual Loopback
Fully Supported
In Hardware mode, dual loopback mode is not supported.
Remote, Analog local, and digital loopback modes are available.
JASEL[1:0]
Per Channel
In Hardware mode, the jitter attenuator selection is a global setting
that applies to all channels.
RxTSEL
Per Channel
In Hardware mode, the receive termination select is a global set-
ting that applies to all channels.
TxTSEL
Per Channel
In Hardware mode, the transmit termination select is a global set-
ting that applies to all channels.
