LMC568 Low Power Phase-Locked Loop

The LMC568 is an amplitude-linear phase-locked loop consisting of a linear VCO, fully balanced phase detectors, and a carrier detect output. LMCMOS™ technology is employed for high performance with low power consumption. The VCO has a linearized control range of ± 30% to allow demodulation of FM and.
