Description

FUNCTIONAL BLOCK DIAGRAMS This series of devices provide the modulator and demodulator for phase-shifted keyed modulated signals.The devices have an on-chip digital-to-analog converter, allowing digital external programming of Bell 212A, CCITT V.22 or V.26 functions.The XR-2123 provides the modulator and demodulator functions.It is adequate for Bell 212A (1200 BPS only) and Bell 201 standards.The XR-2123 requires a synchronous-to-asynchronous converter and scrambler-descrambler for the dig
