PLL Synthesizer

RTx providess standard and custom PLL modules for local oscillators in frequency translation applications.

RTx PLL modules offer the excellent phase noise and spurious performance as fixed frequency or serially programmable frequency sources. These products provide the most suitable solutions for oscillators in communication systems.


  • Excellent phase noise & spurious
  • Frequency range from 20MHz to 6GHz
  • Internal reference & EPROM
  • Low cost & custom design
  • All harmonics are below -20dBc
  • 5 to 40MHz reference clock
  • Operating temp.: -30~+80 degree C


  • Cellular, PCS, UMTS
  • Up/Down Converter
  • Clock & Data retiming circuit
  • Frequency Synthesizer
