Texas Instruments LMX2820EVM RF Synthesizer Evaluation Module (EVM)

Texas Instruments LMX2820EVM RF Synthesizer Evaluation Module (EVM) is designed to evaluate the performance of LMX2820. This board consists of a prototype LMX2820 device. The LMX2820 is a high-performance wideband synthesizer that can generate any frequency from 43.75MHz to 22.4GHz. This synthesizer supports JESD204B compliant SYSREF signal buffering and generation. The LMX2820 allows designers to synchronize the output of multiple instances of the device. The Texas Instruments LMX2820 runs from a single 3.3V supply and has integrated LDOs that eliminates the need for onboard low noise LDOs.

Features

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