Description

FUNCTIONAL BLOCK DIAGRAM The X R-2120 is a self-contained bandpass fi Iter set designed for realization of Bell 212A compatible 1200 bits/sec PSK modems.The XR-2120 utilizes CMOS technology and switched capacitor circuit techniques to minimize external components to a single crystal or frequency source.Contained in the device are two complete bandpass filters centered around the Bell standard 1200 Hz and 2400 Hz send and receive frequencies.These filters also provide compromise line equaliz
