LMC568

Low Power Phase-Locked Loop

General Description

The LMC568 is an amplitude-linear phase-locked loop con-

sisting 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 de-

modulation of FM and FSK signals. Carrier detect is indi-

cated 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.

Features

n Demodulates ±15% deviation FM/FSK signals

n Carrier Detect Output with hysteresis

n Operation to 500 kHz input frequency

n Low THD — 0.5% typ. for ±10% deviation

n 2V to 9V supply voltage range

n Low supply current drain

Typical Application (100 kHz input frequency, refer to notes pg. 3)
