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.

Timing Capacitor (Pins 2 and 3)
The oscillator frequency is inversely proportional to the
timing capacitor, C. The minimum capacitance value is
limited by stray capacitances and the maximum value by
physical size and leakage current considerations.
Recommended values range from 100pF to 100mF. The
capacitor should be non-polarized.
