Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
The T7630 Dual T1/E1 Terminator consists of two independent, highly integrated, software-configurable, full-featured short-haul transceiver/framers. The T7630 provides glueless interconnection from a T1/E1 line to a digital PCM system. Minimal external clocks are needed. Only a system clock/frame sync and a phase-locked line rate clock are required. System diagnostic and performance monitoring capability with integrated programmable test pattern generator/detector and loopback modes is provided.
