APPLICATION INFORMATION
December 1990
Phase-locked-loop with lock detector
(1) To obtain optimum VCO performance, C1 must be as small as possible but larger than 100 pF.
(2) Interpolation for various values of R2 can be easily calculated because a constant R2C2 product will produce

almost the same VCO output frequency.
