Datasheet Summary
XR- 14412
FSK Modem System
GENERAL DESCRIPTION
The XR-14412 contains all the necessary circuitry to construct a plete FSK modulator/demodulator (MODEM) system. Included is circuitry for pinprogrammable frequency bands, either U.S. or foreign (CCITI) standards for low-speed MODEMS. The XR-14412 provides T2L-patible inputs and outputs. Included in the XR-14412 are Features for self-testing and an echo suppression tone generator. The XR-14412 utilizes plementary MOS technology for low-power operation.
