Special Information Tone Detector

Description

Features

The M-984-02 Special Information Tone Detector is a

monolithic integrated circuit designed to provide reli-

able detection of many common telephone network

status signals. In particular, it detects the signals

known as Special Information Tones (SITs) or error

tones as defined by the CCITT, and single tones often

used as dial tone, audible ringing, and other general

progress indications. The M-984-02 uses CMOS

switched capacitor filters and a crystal time base to

achieve the high stability and accuracy specified. Each

tone detection window has an associated output pin,

which can be placed in a high impedance state for use

with time-share microcomputer bus applications.

• Detects single-frequency tones used for error

indication and call progress in telephone systems

• Provides detection windows for:

400/425 Hz (Call Progress)

950 Hz (Special and error indication)

1400 Hz (Special and error indication)

1800 Hz (Special and error indication)

• Separate tri-state outputs for each tone window

• Inexpensive 3.58 MHz crystal time base

• Auxiliary 3.58 MHz clock output

• 14-pin DIP package and 16-pin SOIC package

• Single supply 3 to 5 volt (low power CMOS)

• Wide dynamic range (30 dBm)

In comparison with the earlier M-984, the M-984-02

has wider acceptance bands for SIT tones to facilitate

reception of tape-loop tones, lower power consump-

tion at 5V operation, 3V operation, superior tempera-

ture performance, lower cost, and is available in DIP,

SOIC, and SOIC tape and reel versions.

Applications

• Automatic dialers

• Modems

• Telecom test equipment

• Telephone traffic measurement,

• Service evaluation

• Billing equipment
