It is ideally suited for FM, FSK, and sweep or tone generation, as well as for phase-locked loop applications. ORDERING INFORMATION Part No. XR-2207M XR-2207CP XR-2207D XR-2207ID APPLICATIONS
D FSK Generation D Voltage and Current-to-Frequency Conversion D Stable Phase-Locked Loop D Waveform Generation – Triangle, Sawtooth, Pulse, Squarewave D FM and Sweep Generation The XR-2207 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.
