GENERAL DESCRIPTION

The XRT83SL30 is a fully integrated single-channel short-haul line interface unit for T1(1.544Mbps) 100?, E1(2.048Mbps) 75? or 120? and J1 110? applications.

FEATURES

? Fully integrated single-channel short-haul transceiver for E1,T1 or J1 applications

? Programmable Transmit Pulse Shaper for E1,T1 or J1 short-haul interfaces

? Five fixed transmit pulse settings for T1 short-haul applications plus a fully programmable waveform generator for transmit output pulse shaping

? High receiver interference immunity

? Receive monitor mode handles 0 to 29dB resistive attenuation along with 0 to 6dB of cable attenuation for both T1 and E1 modes

? Supports 75? and 120? (E1), 100? (T1) and 110? (J1) applications.

? Internal and/or external impedance matching for 75?,100?, 110? and 120?.

? Tri-State transmit output and receive input capability for redundancy applications

? Provides High Impedance for Tx and Rx during power off

? Transmit return loss meets or exceeds ETSI 300 166 standard

? On-chip digital clock recovery circuit for high input jitter tolerance

? Crystal-less digital jitter attenuator with 32-bit or 64- bit FIFO Selectable either in transmit or receive path

? On-chip frequency multiplier generates T1 or E1 Master clocks from variety of external clock sources

? On-chip transmit short-circuit protection and limiting, and driver fail monitor output (DMO)

? Receive loss of signal (RLOS) output

? On-chip HDB3/B8ZS/AMI encoder/decoder

? QRSS pattern generation and detection for testing and monitoring

? Error and Bipolar Violation Insertion and Detection
