DESCRIPTION
The 78P2243 is a triple channel version of the 78P2241. Each of the three ports is a line interface transceiver 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. Each receiver recovers clock and data from a B3ZS or HDB3-coded AMI signal. The receiver can compensate for over 12dB of cable and 6dB of flat loss. The transmitter has a B3ZS/HDB3 ENDEC with a receive line code violation detector, a loop-back mode, a clock polarity selection mode, and the ability to receive a DSX3 monitor signal. Signals generated meet the standard pulse shape requirements. The 78P2243 is manufactured in an advanced BiCMOS process and operates at both 3.3V and 5V power supply voltages. BLOCK DIAGRAM
