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 FSK signals. Carrier detect is indicated when the P
LL is locked to an input signal greater than 26 mVrms. LMC568 applications include FM SCA and TV second Audio program decoders, FSK data Demodulators and voice pagers.
