LXT332
Dual T1/E1 Line Interface Unit with Crystal-less Jitter Attenuation
Datasheet
The LXT332 is a fully integrated Dual Line Interface Unit (DLIU) for both 1.544 Mbps (T1) and
2.048 Mbps (E1) applications. It features B8ZS/HDB3 encoders and decoders, and a constant
low output impedance transmitter for high return loss. Transmit pulse shape is selectable for
various line lengths and cable types.
The LXT332 incorporates an advanced crystal-less digital jitter attenuator, switchable to either
the transmit or receive side. This eliminates the need for an external quartz crystal. It offers
both a serial interface (SIO) for microprocessor control and a hardware control mode for stand-
alone operation.
The LXT332 offers a variety of advanced diagnostic and performance monitoring features. It
uses an advanced double-poly, double-metal CMOS process and requires only a single 5-volt
power supply.

Bipolar Violation Insertion
The same pins which provide the high frequency clocks can also be used to insert bipolar violations
into the outgoing data stream. Violations can be inserted into each LIU port independently.
Built-In Self Test (QRSS)
The LXT332 can generate and transmit a Quasi Random Signal Source (QRSS) pattern to Built-In
Self Test (BIST) applications. Logic errors and bipolar violations can be inserted into the QRSS
output. The LXT332 also detects QRSS pattern synchronization and reports bit errors in the
received QRSS pattern data stream.
AIS Detection
The LXT332 detects the AIS alarm signal on the receive side independent of the loopback modes.
When AIS is detected (less than 3 zeros in 2048 bits), the LXT332 provides an indicator output.
