KT3170 LOW POWER DTMF RECEIVER
INTRODUCTION
The KT3170 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 seperates
counting section which verifies the frequency and
duration of the received tones before passing the cor-
responding 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 cystal as
an external component.
FEATURES
Detects all 16 standard tones.
Low power consumption : 15mW (Typ)
Single power supply : 5V
Uses inexpensive 3.58MHz crystal
Three state outputs for microprocessor interface
Good quality and performance for using in
exchange system
Power down mode/input inhibit
