M-982-02
Precise Call Progress Tone Detector
Description
The M-982-02 is an integrated circuit precise tone
detector for special-purpose use in automatic following
of switched telephone calls. The circuit uses low-
power CMOS techniques to provide the complete fil-
tering and control required for this function. The basic
timing of the M-982-02 is designed to permit operation
with almost any progress tone system.The use of inte-
grated circuit techniques allows the M-982-02 to pack
the five filters for call progress following into a single
22-pin DIP or 20-pin SOIC. A 3.58 MHz crystal-con-
trolled time base guarantees accuracy and repeatabil-
ity.
The M-982-02 is an enhanced drop-in replacement for
the M-982-01. It has a wider operating voltage range
(down to 3V). It has lower power consumption under
normal operating conditions. In addition, a power-
down (PD) feature is provided to further reduce power
consumption when inactive. It includes a 425 Hz
detector to support common international call progress
requirement.

Funtion
Active high tri-state output, detect for 350 Hz.
Active high tir-state ooutput, detect for 400/620 Hz.
(See Note.)
Active high tri-state output, detect for 440 Hz.
Active high tri-state output, detect for 480 Hz.
Active high tri-state output, detect for 425 Hz.
Active high enabled, when low drives STROBE low.
Active high input. When low tri-state DET n pins.
Analog signal input (internally capacitive coupled).
Active high output, indicates valid DET n.
Most positive power supply input pin.
Internally generated mid-power supply voltage
(output).
Most negative power supply input pin.
Buffered oscillator output (3.58 MHz).
Crystal oscillator or digital clock input.
Crystal oscillator output. Used only with a crystal.
Use X358 when clock output signal is required.
Active low input. Adds 10 dB of gain to input stage.
Compatibility selection. Connection to VSS selects
400 Hz detection. (M-981-02 emulation.) Connection
to VDD or no connection selects 620 Hz detection.
Power-down operation, logic high inhibits internal
clock. Internal pulldown resistor.
Note: This output indicates 400 Hz detect when MODE is connected to VSS and 620
Hz detect when open, or connected to VDD.
