XR-C240
Monolithic PCM Repeater
GENERAL DESCRIPTIDN
The XR-C240 is a monolithic repeater circuit for PulseCode Modulated (PCM) telephone systems. It is designed to operate as a regenerative repeater at 1.544 Megabits per second (Mbps) data rate on Tl-type PCM Iines_
The XR-C240 monolithic IC is packaged in a hermetic 16Pin DIP package, and is designed to operate over a temperature range of -40°C to +85°C. It contains all the basic functional blocks of a regenerative repeater system including Automatic Line Bu ild-Out (A LBO) and equal ization, and is insensitive to reflections caused by cable discontinuities.
