T7630 Dual T1/E1 5.0 V Short-Haul Terminator (Terminator-II)
Features
The T7630 Dual T1/E1 Terminator consists of two
independent, highly integrated, software-config-
urable, 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. Sys-
tem diagnostic and performance monitoring capabil-
ity with integrated programmable test pattern
generator/detector and loopback modes is provided.

Programmable, independent transmit and receive
system interfaces at a 2.048 MHz, 4.096 MHz, or
8.192 MHz data rate.
System interface master mode for generation of
system frame sync from the line source.
Internal phase-locked loop (with external VCXO)
for generation of system clock from the line source.
