LMC568 Datasheet Low Power Phase-locked Loop

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LMC568 Low Power Phase-Locked Loop May 1999 LMC568 Low Power Phase-Locked.

General Description

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.

Key Features

  • n n n n n n Demodulates ± 15% deviation FM/FSK signals Carrier Detect Output with hysteresis Operation to 500 kHz input frequency Low THD.
  • 0.5% typ. for ± 10% deviation 2V to 9V supply voltage range Low supply current drain Typical.
