MV5089 Overview
MV5089 MV5089 DTMF GENERATOR The MV5089 is fabricated using Plessey Semiconductors' ISO-CMOS high density technology and offers low power and wide voltage operation. An inexpensive 3.58MHz TV crystal pletes the reference oscillator. From this frequency are derived 8 different sinusoidal frequencies which, when appropriately mixed, provide Dual-Tone MultiFrequency (DTMF) tones.
