XRT83L34 QUAD T1/E1/J1 LH/SH TRANSCEIVER

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 (equi.

XRT83L34 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 r
