T1 Line Interface The CS61544 combines the analog transmit and receive line interface functions for a T1 system interface in one 28 pin device. The T1 line interface operates from a single 5V supply, is transparent to the T1 framing format, and can work with ABAM and other cable types. Crystal's SMART Analog circuitry shapes the transmit pulse internally, providing the appropriate pulse shape at the DSX-1 cross-connect for the line lengths ranging from 0 to 655 feet. Maximum range is greater than 1500 feet. The transmitter uses an elastic store to remove jitter from the outgoing data prior to transmission. Features Provides analog T1 line interface Fully compatible with CB119, Publication 43802, & TR-TSY-000009 Programmable pulse-shaping line driver Performs data and timing recovery DIP-28 Applications Interfacing networking equipment such as M13 multiplexers to a DSX-1 Cross Connect Interfacing fiber optic transmission equipment to T1 lines
