Phase Locked Loops

Demodulate signals and generate stable frequencies

Acting as an oscillator feedback system, PLLs comprise phase comparator, loop filter and voltage controlled oscillator (VCO). Our devices offer low power consumption, excellent VCO frequency linearity and are user configurable.

Key features and benefits

  • Wide supply voltage 3.0 to 6.0 V
  • Max. frequency up to 17 MHz (typ.)
  • Low power consumption
  • Excellent VCO frequency linearity
  • Choice of phase comparators
  • User configurable

Key applications

  • FM modulation and demodulation
  • Frequency synthesis and multiplication
  • Clock recovery
  • Data synchronization and conditioning
  • Voltage-to-frequency conversion
  • Motor-speed control.interface
