Combination of Exar XR-2207 VCO and XR-2208 operational multiplier is connected for operation from single 12-24 V supply for data communication and signal conditioning applications. Operating frequency range is 0.01 Hz to 100 kHz. Timing resistor R0 should be in range of 5K to 100K, and R1 should be greater than R0 For 10-kHz center frequency, C0 can be 0.01 μF and R0 can be 10K. R1 and C1 which determine tracking range and low-pass filter characteristics, are 45κ and 0.032 μF．－ Phase-Locked Loop Data Book, Exar Integrated Systems, sunnyvale, CA, 1978, p62－64
