... The MV5089 is fabricated using ISO-CMOS high density technology and offers low power and wide voltage operation. An inexpensive 3.58MHz TV crystal completes the reference oscillator. From this frequency are derived 8 different sinusoidal frequencies which, when appropriately mixed, provide Dual-Tone Multi-Frequency (DTMF) tones. Inputs are compatible with a standard 2-of-8 active-low ...

OUTPUT FREQUENCY Table 1 shows the output frequency deviation from the standard DTMF frequencies when a 3.58MHz crystal is used as the reference. The row and column output waveforms are digitally synthesised using R-2R D-to-A converters (see Fig.3), resulting in ...

... A single Row tone only may be generated by connecting 2 columns, and the desired row OUTPUT TONE LEVEL The output tone level of the MV5089 is proportional to the applied DC supply voltage. A regulated supply will normally be used which may be designed to provide stability over the temperature range. V ...
