LXT312A/315A
- Low Power T1 PCM Repeaters/Transceivers
Note - Not recommended for new designs.
The LXT312A and LXT315A are integrated repeater/transceiver circuits for T1 carrier systems. The LXT312A is a dual repeater/ transceiver and the LXT315A is a single repeater/transceiver. The LXT312A and LXT315A are designed to operate as regenerative repeaters/transceivers for 1.544 Mbps data rate PCM lines. Each includes all circuits required for a regenerative repeater/transceiver system including the equalization network, automatic line build-out (ALBO), and a state-of-the-art analog/digital clock extractionnetwork tuned by an external crystal. The key feature of the LXT312A family is that it requires only a crystal and a minimum of other components to complete a repeater/transceiver design. Compared with traditional tuned coil-type repeaters/transceivers, they offer significant savings in component and labor costs, along with reduced voltage drop/power consumption, and improved reliability. To ensure performance for all loop lengths, the LXT312A and LXT315A are 100% AC/DC tested using inputs generated by Cortina's proprietary transmission line and network simulator. The LXT312A and LXT315A are advanced CMOS devices which require only a single 5-volt power supply.
