.. PRELIMINARY REV. P1.3.4 QUAD T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR FEBRUARY 2004 GENERAL DESCRIPTION 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 1024kHz in E1 mode. In T1 applications, the XRT83L34 can generate five transmit pulse shapes to meet the short-haul Digital Cross-Connect (DSX-1) template requirements as well...
