Exar Corporation XRT82L24
The XRT82L24 is a fully integrated Quad (four channels) short-haul line interface unit for E1(2.048Mbps) 75Ω or 120Ω applications. Each channel consists of a receiver with equalizer for reliable data and clock recovery, and a transmitter which accepts either single or dual-rail digital inputs for signal transmission to the line using a low output impedance line driver. The device also includes a crystal-less jitter attenuator which, depending on system requirements, can be selected in the receive or transmit path through the Host or Hardware Mode control.| Part No. | XRT82L24 |
