9.8 GHz RF High Performance Synthesizer Operating From a Buck Converter Reference Design


Design files


The TIDA-00885 design utilizes the LMX2592 a low-noise, wideband RF PLL with integrated VCO that can produce an output frequency range from 20 MHz to 9.8 GHz. The LMX2592 has excellent performance, integrated phase noise of 49fs for 6GHz output making it an ideal low noise source. There are two options to power the LMX2592 frequency synthesizer,  the TPS62150 and LM43601 buck converters, two commonly used footprints.  The LM43601 is pin-to pin-compatible with LM46000, LM46001, LM46002, LM43600, LM43602, and LM43603. The TPS62150 DC-DC regulator is pin-to-pin compatible with TPS6213x, TPS6214x devices.

  • Output Frequency Range from 20 to 9800MHz
  • Input Clock Frequency from 5 MHz to 1400MHz
  • Industry Leading Phase Noise Performance
  • Up to 95% efficiency to step down the voltage from 5V to 3.3V using on-board DC-DC Regulator
  • On-board DC-DC regulators are footprint compatible with several other regulators
