M-991 Call Progress Tone Generator Features Generates standard call progress tones Digital input control Linear (analog) output Power output capable of driving standard line 14-pin DIP and 16-pin SOIC package types Single supply 5V CMOS (low power) Inexpensive 3.58 MHz time base Temperature range from -25ºC to 70ºC (-01 version) • Temperature range from -40ºC to 85ºC (-02 version) • • • • • • • • Applications • • • • • Telephone systems Test equipment Callback Security systems Billing systems Description The M-991 is a call progress tone generator integrated circuit for use in telephone systems. The circuit uses low-power CMOS techniques to generate tones which are digitally controlled and highly linear. The M-991 is designed to permit operation with almost any system. The use of integrated circuit techniques allows the M991 to incorporate the control, tone generating, and power output buffer into a single 14-pin DIP or a 16-pin SOIC. A 3.58-MHz (color burst) crystal-controlled time base guarantees accuracy and repeatability.

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: 1. Exceeding these ratings may permanently damage the M-991.

Calling parties can identify the success of a placed call by what is heard after dialing. The M-991 series utilizes a highly linear tone generator that produces the unique frequencies (singly or in pairs) that are common to call progress signals. Duration and frequency selection are digitally controlled (see the Data/Tone Selection table below for data settings for a particular tone output). A typical control sequence for the M-991 is: (1) set data lines to desired frequency selection, (2) wait for data lines to settle, (3) drive the chip enable (CE) low, (4) maintain CE low for desired tone duration (Note: data lines may be changed after data hold time), and (4) return CE to Data/Tone Selection D0 0 0 0 0 0 0 0 0 1 1 D1 0 0 0 0 1 1 1 1 0 0 D2 0 0 1 1 0 0 1 1 0 0 D3 0 1 0 1 0 1 0 1 0 1 Frequency (Hz) 1 2 350 440 400 off 440 off 440 480 440 620 480 off 480 620 350 off 620 off 941 1209 Use Dial Tone Special Alert Tone Audible Ring Pre-empt Bell high tone Reorder(Bell low) Special Special DTMF “*” a logic high. (Commonly used call progress tones are shown in the Data/Tone Selection table below.) In a bus-oriented system, noise on the data lines may propagate through the device and appear at the output. To safeguard against this, use an external latch to lock the data into the device. In addition, it is good practice to bypass the VREF pin to ground with a small capacitor (0.01 mF) to reduce power supply noise. The designer should be aware of device timing requirements and design accordingly. The data input pins may be tied high (+5 VDC) or low (ground) as required, but D4 and D5 must be left open. Beware of hardwiring the CE pin for dedicated tone generation. This input is edge triggered. An RC network like that shown in the Power-on Reset Circuit on Page 4 should be used to momentarily reset the device immediately following power-up to ensure proper operation.
