Product Summary
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 PLL 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.
