Key Document


The LMX2594EVM evaluation module is for the LMX2594 device. The LMX2594 device is the first PLL with an integrated voltage-controlled oscillator (VCO) in the industry to get fundamental VCO output up to 15 GHz. The industry leading PLL figure of merit (FOM) is –236 dBc/Hz with 1/f of –129 dBc/Hz. This device supports JESD204B standard (it can generate or repeat the SYSREF signal) which makes it ideal to clock high-speed data converters. The integrated jitter from the EVM measurements is less than 50 fs at a 9-GHz carrier frequency. By providing a SYNC signal, the user can synchronize the output phase across multiple LMX2594 devices. The LMX2594 device can also generate a frequency ramp that can be demonstrated in this evaluation module. With an onboard oscillator, the setup process only requires a 3.3-V power supply and the included Reference Pro module (for the SPI programming interface). The software is simple with an intuitive and user-friendly GUI.

  • 10-MHz to 15-GHz output frequency 
  • –110-dBc/Hz phase noise at 100-kHz offset with 15-GHz carrier
  • 45-fs rms jitter at 7.5 GHz (100 Hz to 100 MHz) 
  • Two differential outputs with programmable output power up to 7 dBm at 15 GHz 
  • A complete circuit for the synthesizer that is optimized and tested for performance and includes a USB programming module

What's Included

  • Reference Pro
