Overview
MV8865 MV8865 DTMFFILTER The MV8865 contains both the high group and low group filtering and comparator functions required to implement a Dual Tone Multi Frequency tone receiver using a DTMF Digital Detector (Le.
MV8860/62/63).
Switched capacitor techniques are used to implement the filters and the deviceJs fabricated using Plessey Semiconductors' high density ISO/CMOS technology.
The filter clocks are derived from an on-chip oscillator requiring only a low cost TV crystal as an external component.
The MV8865 offers single supply operation over a wide supply voltage range and incorporates a logical power down facility.
FEATURES • Provides DTMF High and Low Group Filtering • Hard Limiting o...
