GENERAL DESCRIPTION
The XR-2207 is a monolithic voltage-controlled oscillator
(VCO) integrated circuit featuring excellent frequency
stability and a wide tuning range. The circuit provides
simultaneous triangle and squarewave outputs over a
frequency range of 0.01Hz to 1MHz. It is ideally suited for
FM, FSK, and sweep or tone generation, as well as for
phase-locked loop applications.
The XR-2207 has a typical drift specification of 20ppm/
°
C.
The oscillator frequency can be linearly swept over a
1000:1 range with an external control voltage; and the
duty cycle of both the triangle and the squarewave
outputs can be varied from 0.1% to 99.9% to generate
stable pulse and sawtooth waveforms.
