XRT83L30 Datasheet Single-channel T1/e1/j1 Lh/sh Transceiver

Manufacturer: Exar (now MaxLinear)

Overview: .. áç MAY 2003 PRELIMINARY XRT83L30 REV. P1.3.0 SINGLE-CHANNEL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR.

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.

In long-haul applications the XRT83L30 accepts signals that have passed through cables from 0 feet to over 6000 feet in length and have been attenuated by 0 to 45dB at 772kHz in T1 mode or 0 to 43dB at 1024kHz in E1 mode.

In T1 applications, the XRT83L30 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 75Ω, 100Ω, 110Ω and 120Ω for both transmitter and receiver. For the receiver this is accomplished by internal resistors or through the combination of one single fixed value external resistor and programmable internal resistors. In the absence of the power supply, the transmit output and receive input are tri-stated allowing for redundancy.
