LXT310
T1 CSU/ISDN PRI Transceiver
Datasheet
The LXT310 is the first fully integrated transceiver for T1 CSU and ISDN Primary Rate
Interface (ISDN PRI) applications at 1.544 Mbps. This transceiver operates over 6,000 feet of 22
AWG twisted-pair cable without any external components. To compensate for shorter lines, 7.5
dB, 15 dB, and 22.5 dB frequency-dependent transmit Line Build-Outs (LBOs) are provided.
The device offers selectable B8ZS encoding/decoding, and unipolar or bipolar data I/O. The
LXT310 also provides jitter attenuation in either the transmit or receive direction starting at 6
Hz, and incorporates a serial interface (SIO) for microprocessor control.
The LXT310 offers a variety of diagnostic features including loopbacks and loss of signal
monitoring. It uses an advanced double-poly, double-metal CMOS process and requires only a
single 5-volt power supply.
