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.

TheXR-2207hasatypicaldriftspecificationof20ppm/°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.
