GL6850 General Description
The GL6850 tone ringer is a monolithic device, which incorporates two oscillators, and output amplifier and a power supply control circuit. The o scillator 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.c. supply. The power control circuit has builtin hysteresis to prevent false triggering and rotary dial chirps. The GL6850 can be triggered externally under logic control.

GL6851 General Description
The GL6851 tone ringer is a monolithic device, which incorporates two oscillators, an 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.c. supply. The GL6851 has provision for adjustment of the supply initiation current.
