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 (equivalent of 0 to 6000 feet of cable loss) or 0 to 43dB at 1024.
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 redundancy applications The chip includes an integrated programmable clock multiplier that can synthesize T1 or E1 master clocks from a variety of external clock sources.
APPLICATIONS
• T1 Digital Cross-Connects (DSX-1)
• ISDN Primary Rate Interface
• CSU/DSU E1/T1/J1 Interface
• T1/E1/J1 LAN/WAN R.
