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 .
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 applications. The chip includes an integrated programmable clock multiplier that can synthesize T1 or E1 master clocks from a.
