XR2209
FEATURES
D Excellent Temperature Stability (20ppm/°C) D Linear Frequency Sweep D Wide Sweep Range (1000:1 Minimum) D Wide Supply Voltage Range (+4V to +13V) D Low Supply Sensitivity (0.1% /V) D Wide Frequency Range (0.01Hz to 1MHz) D Simultaneous Triangle and Squarewave Outputs 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
APPLICATIONS D Voltage and Current-to-Frequency Conversion D Stable Phase-Locked Loop D Waveform Generation Triangle, Sawtooth, Pulse, Squarewave D FM and Sweep Generation 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...
