XRT83L38, OCTAL T1/E1/J1 LH/SH TRANSCEIVER

The XRT83L38 is a fully integrated Octal (eight 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 XRT83L38 accepts signals that have been attenuated from 0 to 36dB at 772kHz in T1 mode (eq

XRT83L38 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. In the absence of the power supply, the transmit outputs and receive inputs are tri-stated allowing for re
