XR-14412 - FSK Modem System

Description

The XR-14412 contains all the necessary circuitry to construct a complete FSK modulator/demodulator (MODEM) system.

Included is circuitry for pinprogrammable frequency bands, either U.S.

or foreign (CCITI) standards for low-speed MODEMS.

Features

  • for self-testing and an echo suppression tone generator. The XR-14412 utilizes complementary MOS technology for low-power operation.
