TWO TONE RINGER
Description
The GL6850 tone ringer is a monolithic device, which incorporates two oscillators, and output amplifier and a power supply control circuit.
The oscillator frequencies can be adjusted over a wide range by selection of external components.
One oscillator, normally operated at a low frequency, causes the second oscillator to alternate between its nominal frequency and a related higher frequency.
The resulting output is a distinct warbling tone.
The output amplifier will drive either a transformer coupled loudspeaker or a piezo-ceramic transducer.
The device can be powered from a telephone line or a fixed d.
