Order now


This evaluation module is for the LMX2820, which is a 22.6-GHz wideband RF synthesizser. This synthesizer supports JESD204B compliant SYSREF signal buffering and generation. The LMX2820 allows designers to synchronize the output of multiple instances of the device.

  • 22.6-GHz output
  • 40-fs RMS jitter (10 kHz - 20 MHz) at 6-GHz carrier
  • Synchronization of output phase across multiple devices
  • Support for SYSREF
  • Support external VCO input up to 22.6 GHz
  • This evaluation module has the complete circuit for the synthesizer, optimized and tested for performance, and includes a USB programming module
