XR-C262Z
XR-C262Z is High-Performance PCM Repeater manufactured by Exar.
DESCRIPTION
FUNCTIONAL BLOCK DIAGRAM
The XR-C262Z is a high-performance monolithic repeater IC for pulse-code modulated (PCM) telephone systems. It is designed to operate as a regenerative repeater at 1.544 Megabits per second (Mbps) data rate on T1-type PCM lines.
PREAMP OUT
The X R-C262Z operates with a single 6.8 volt power supply, and with a typical supply current of 13 m A. It provides bipolar output drive with high-current handlinq capability. The clock-extractor section of XR-C262Z uses the resonant-tank circu it principle, rather than the injection-locked oscillator technique used in earlier monolithic repeater designs. The bipolar output drivers are designed to go to their "off" state automatically, when there is no input signal present.
