GENERAL DESCRIPTION
The XR-2209 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 oscillator of the XR-2209 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.
