GENERAL DESCRIPTION
The XRT83SL30 is a fully integrated single-channel short-haul line interface unit for T1(1.544Mbps) 100Ω, E1(2.048Mbps) 75Ω or 120Ω and J1 110Ω 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 75Ω and 120Ω (E1), 100Ω (T1) and 110Ω (J1) applications.
• Internal and/or external impedance matching for 75Ω,100Ω, 110Ω and 120Ω.
• 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
