MT8840 - ISO2-CMOS Data Over Voice Modem

Description

The MT8840 is a carrier over voice modem which allows simultaneous transfer of voice and data over a single pair of wires.

Data is transferred on an amplitude shift keyed (ASK) 32 kHz carrier.

Features

  • Performs ASK (amplitude shift keyed) modulation and demodulation 32 kHz carrier frequency Up to 2 kbit/s full duplex data transfer rate On-chip oscillator On-chip tone caller for alerting functions Adjustable tone caller frequencies Selectable self-loop test mode 5V/2.5mA power supply ISO2 -CMOS and switched capacitor technologies 18 Pin DIP MT8840AE MT8840AS ISSUE 4 November 1990 Ordering Info.
