Special Information Tone Detector
Description
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.
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.

Pin Functions
PIN FUNCTION
XIN
XOUT
Crystal Connection — 3.58 MHz crystal across these pins will produce the timebase needed for proper operation of the
M-984-02. An external clock signal may be fed to XIN providing the clock signal has a duty cycle of 50 ±10% and comes within
0.2 volts of the supply rails. XOUT remains unconnected when an external clock is used.
X358 A buffered output pin. A 3.58 MHz clock signal is available for use in other circuits as a timebase. Leave open when unused.
ENVLP
VSS
VDD
SIGIN
The ENVLP pin is a common detection indicator for the four detect pins. Simply put, the ENVLP is a logical “OR” of the active
detect circuits for each of the four windows, though there is a delay provided to permit ENVLP to latch the first active detect pin.
ENVLP is not tri-state controlled.
The power supply pins, VDD being the most positive. Commonly, VDD is at 3-5 volts, white VSS is at ground.
Analog signal input. (Internally capacitively coupled.)
VREF VREF is a bias voltage generated in the chip for use in external analog circuits, such as active filters and AC-coupled buffers.
Leave open when unused.
OE The tri-state control pin. OE places the DET pins in the active mode when at logic “1”. When at logic “0,” OE causes the DET
outputs to appear as high impedance. Should be tied to logic “1” when the M-984-02 is not used in a time-shared bus
application.
D1800
D1400
D950
D400
The detect outputs associated with each window. Tri-state control is available through use of the OE pin.
Timing is shown in the Timing Diagram on page 4.
