XR2207 Voltage Controlled Oscillator IC14, R32

DescriptionThe XR2207 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.FEATURESExcellent Temperature Stability (20ppm/°C)Linear Frequency SweepAdjustable Duty Cycle (0.1% to 99.9%)Two or Four Level FSK CapabilityWide Sweep Range (1000:1 Minimum)Logic Compatible Input and Output LevelsWide Supply Voltage Range (4V to 13V)Low Supply Sensitivity (0.1% /V)Wide Frequency Range (0.01Hz to 1MHz)Simultaneous Triangle and Squarewave OutputsAPPLICATIONSFSK GenerationVoltage and Current-to-Frequency ConversionStable Phase-Locked LoopWaveform Generation:Triangle, Sawtooth, Pulse, SquarewaveFM and Sweep GenerationDocument:Datasheet
