The 78P7200L is a line interface transceiver IC for E3, DS3, STS-1, North America T3 and ATM applications. It includes clock recovery and transmitter pulse shaping functions for applications using 75-ohm coaxial cable at distances up to 1100 feet. These applications include DSLAMs, T3/E3 digital multiplexers, SONET Add/Drop multiplexers, PDH equipment, DS3 to Fiber optic and microwave modems and ATM WAN access for routers and switches.
The receiver of the 78P7200L recovers clock and positive data and negative data from an AMI signal. It can compensate for over 12dB of cable and 6dB of flat loss. The transmitter generates a signal that meets the standard pulse shape requirements.
The 78P7200L is pin and functionally compatible to the 78P7200. It adds loop-back and clock polarity selection.
The 78P7200L is manufactured in an advanced BICMOS process and operates at both 5V and 3.3 V power supply voltages. It consumes less than 95 mA of supply current.
