XRT83L30 Product details

GENERAL DESCRIPTION
The XRT83L30 is a fully integrated single-channel long-haul and 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 long-haul and short-haul transceiver for E1,T1 or J1 applications.
• Adaptive Receive Equalizer for cable attenuation of up to 45dB for T1 and 43dB for E1.
• 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.
• Programmable Transmit Line Build-Outs (LBO) for T1 long-haul application from 0dB to -22.5dB in three 7.5dB steps.
• Tri-State transmit output and receive input capability for redundancy applications
• Selectable receiver sensitivity from 0 to 36dB or 0 to 45dB cable loss for T1 @772kHz and 0 to 43dB for E1 @1024kHz.
• 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 external impedance matching for 75Ω,100Ω, 110Ω and 120Ω.
• 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
• Receiver Line Attenuation Indication Output in 1dB steps
• Network Loop-Code Detection for automatic Loop-Back Activation/Deactivation
• Transmit All Ones (TAOS) and In-Band Network Loop Up and Down code generators
• Supports Analog, Remote, Digital and Dual Loop-Back Modes
• Meets or exceeds T1 and E1 short-haul and long-haul network access specifications in ITU G.703, G.775, G.736 and G.823; TR-TSY-000499; ANSI T1.403 and T1.408; ETSI 300-166 and AT&T Pub 62411
• Supports both Hardware and serial Microprocessor interface for programming
• Programmable Interrupt
• Low power dissipation
• Logic inputs accept either 3.3V or 5V levels
• Single +3.3V Supply Operation
• 64 pin TQFP package
• -40°C to +85°C Temperature Range

APPLICATIONS
• T1 Digital Cross-Connects (DSX-1)
• ISDN Primary Rate Interface
• CSU/DSU E1/T1/J1 Interface
• T1/E1/J1 LAN/WAN Routers
• Public switching Systems and PBX Interfaces
• T1/E1/J1 Multiplexer and Channel Banks
