·Wireless Base Station interface
·T1 LAN/WAN bridge/routers
·T1 Mux; Channel Banks
·Digital Loop Carrier - Subscriber Carrier Systems


Specifications

Parameter Sym Min Max Unit
DC supply (reference to GND) VCC, TVCC 6.0 V
Input voltage, any pin 1 VIN GND - 0.3 V VCC + 0.3 V V
Input current, any pin 2 IIN - 10 10 mA
Storage Temperature TSTG -65 150 °C
Caution: Exceeding these values may cause permanent damage.
Caution: Functional operation under these conditions is not implied.
Caution: Exposure to maximum rating conditions for extended periods may affect device reliability.
1. TVCC and VCC must not differ by more than 0.3 V during operation. TGND and GND must not differ by more than 0.3during operation.
2. Transient currents of up to 100 mA will not cause SCR latch-up. TTIP, TRING, TVCC, and TGND can withstand continuous currents of up to 100 mA.



Description

The LXT362 is a fully integrated, combination transceiver for T1 ISDN Primary Rate Interface and general T1 long and short haul applications. It operates over 22 AWG twisted-pair cables from 0 to 6 kft and offers Line Build Outs and pulse equalization settings for all T1 Line Interface Unit (LIU) applications. LXT362 provides both a serial port for microprocessor control (Host mode) as well as standalone operation (Hardware mode).

The device LXT362 incorporates advanced crystal-less digital jitter attenuation in either the transmit or receive data path starting at 3 Hz. B8ZS encoding/decoding and unipolar or bipolar data I/O are selectable. Loss of signal monitoring and a variety of diagnostic loopback modes can also be selected.
