Overview for RF phase locked loops and synthesizers

Low power

Wide range of low power phase locked loops (PLLs) and synthesizers (PLLs with integrated VCOs) for hand held applications.

  • Low power PLLs starting at 5 mA current consumption
  • Low power synthesizers (PLL + VCO) starting at 17 mA
  • Wide choice of low power PLLs with/without integrated VCOs
  • Application specific features like FSK modulation
