S5T3170X01-D0B0 fiche technique
LOW POWER DTMF RECEIVER
INTRODUCTION
The S5T3170 is a complete Dual Tone Multiple Frequency (DTMF)
receiver that is fabricated by low power CMOS and the Switched-
Capacitor Filter technology. This LSI consists of band split filters,
which separates counting section which verifies the frequency and
duration of the received tones before passing the corresponding code
to the output bus. It decodes all 16 DTMF tone pairs into a 4bits digital
code. The externally required components are minimized by on chip
provision of a differential input AMP, clock oscillator and latched three
state interface. The on chip clock generator requires only a low cost
TV crystal as an external component.
