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
- 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.
