It uses this power to activate a tone generator and drive a piezo-ceramic transducer. The tone generation circuitry includes a relaxation oscillator and frequency dividers which produce high and low frequency tones as well as the tone warble frequency. The relaxation oscillator frequency fo is set by resistor R2 and capacitor C2 connected to Pin RC. The oscillator will operate with fo from 1.0 kHz to 10 kHz with the proper choice of external components (see Figure 1). The frequency of the tone ringer output signal at RO1 and RO2 alternates between fo/4 to fo/5. The warble rate at which the frequency changes is fo/320 for the MC34017-1, fo/640 for the MC34017-2 and fo/160 for the MC34017-3. With a 4.0 kHz oscillator frequency, the MC34017-1 produces 800 Hz and 1000 Hz tones with a 12.5 Hz warble rate. The MC34017-2 generates 1600 Hz and 2000 Hz tones with a similar 12.5 Hz warble frequency from an 8.0 kHz oscillator frequency. The MC34017-3 will produce 400 Hz and 500 Hz tones with a 12.5 Hz warble rate from a 2.0 kHz oscillator frequency. The tone ringer output circuit can source or sink 20 mA with an output voltage swing of 37 V peak-to-peak. Volume control is readily implemented by adding a variable resistance in series with the piezo transducer. Input signal detection circuitry activates the tone ringer output when the ac line voltage exceeds programmed threshold level. Resistor R3 determines the ringing signal amplitude at which an output signal at RO1 and RO2 will be generated. The ac ringing signal is rectified by the internal diode bridge. The rectified input signal produces a voltage across R3 which is referenced to RG. The voltage across resistor R3 is filtered by capacitor C3 at the input to the threshold circuit. Figure 1. Oscillator Period (1/fo) versus Oscillator R2 C2 Product 800 1/fo, OSCILLATOR PERIOD ( s) When the voltage on capacitor C3 exceeds 1.2 V, the threshold comparator enables the tone ringer output. Line transients produced by pulse dialing telephones do not charge capacitor C3 sufficiently to activate the tone ringer output. Capacitors C1 and C4 and resistor R1 determine the 10 V, 24 Hz signature test impedance. C4 also provides filtering for the output stage power supply to prevent droop in the square wave output signal. Six diodes in series with the rectifying bridge provide the necessary non-linearity for the 2.5 V, 24 Hz signature tests. An internal shunt voltage regulator between the RI and RG terminals provides dc voltage to power the output stage, oscillator and frequency dividers. The dc voltage at RI is limited to approximately 22 V in regulation. To protect the IC from telephone line transients, an SCR is triggered when the regulator current exceeds 50 mA. The SCR diverts current from the shunt regulator and reduces the power dissipation within the IC. EXTERNAL COMPONENTS R1 Line Input Resistor R1 affects the tone ringer input impedance. It also influences ringing threshold voltage and limits current from line transients. (Range: 2.0 to 10 k). Line Input Capacitor C1 ac couples the tone ringer to the telephone line and controls ringer input impedance at low frequencies. (Range: 0.4 to 2.0 F). Oscillator Resistor (Range: 150 to 300 k). Oscillator Capacitor (Range: 400 to 3000 pF). Input Current Sense Resistor R3 controls the ringing threshold voltage. Increasing R3 decreases the ring-start voltage. (Range: 5.0 to 18 k). Ringing Threshold Filter Capacitor C3 filters the ac voltage across R3 at the input of the ringing threshold comparator. It also provides dialer transient rejection. (Range: 0.5 to 5.0 F). Ringer Supply Capacitor C4 filters supply voltage for the tone generating circuits. It also provides an ac current path for the 10 Vrms ringer signature impedance. (Range: 1.0 to 10 F).
