XRT83L34 Datasheet Quad T1/e1/j1 Lh/sh Transceiver

Manufacturer: Exar (now MaxLinear)

Overview: .. PRELIMINARY XRT83L34 REV. P1.3.4 QUAD T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR FEBRUARY 2004.

General Description

The XRT83L34 is a fully integrated Quad (four channel) long-haul and short-haul line interface unit for T1 (1.544Mbps) 100Ω, E1 (2.048Mbps) 75Ω or 120Ω, or J1 110Ω applications.

In long-haul applications the XRT83L34 accepts signals that have been attenuated from 0 to 36dB at 772kHz in T1 mode (equivalent of 0 to 6000 feet of cable loss) or 0 to 43dB at 1024kHz in E1 mode.

In T1 applications, the XRT83L34 can generate five transmit pulse shapes to meet the short-haul Digital Cross-Connect (DSX-1) template requirements as well as for Channel Service Units (CSU) Line Build Out (LBO) filters of 0dB, -7.5dB -15dB and -22.5dB as required by FCC rules.

Key Features

  • as well as transmit driver short circuit detection and receive loss of signal monitoring. It supports internal impedance matching for 75 Ω, 100Ω, 110Ω and 120Ω for both transmitter and receiver. In the absence of the power supply, the transmit outputs and receive inputs are tri-stated allowing for redundancy.
