M-984-02 Special Information Tone Detector Features • 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) Applications • • • • • • Automatic dialers Modems Telecom test equipment Telephone traffic measurement, Service evaluation Billing equipment Description The M-984-02 Special Information Tone Detector is a monolithic integrated circuit designed to provide reliable 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 consumption at 5V operation, 3V operation, superior temperature performance, lower cost, and is available in DIP, SOIC, and SOIC tape and reel versions.

Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability. Note: Exceeding these ratings may permanently damage the device.

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. A buffered output pin. A 3.58 MHz clock signal is available for use in other circuits as a timebase. Leave open when unused. 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 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. 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. 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.
