Overview

The LMX2594EVM evaluation module (EVM) is a platform for developing the LMX2594. LMX2594 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.

Features
  • 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

  • Reference Pro
  • LMX2594EVM

Release Infomation

Improvements

  • See release notes for complete list of updates
  • New Log Options dialog
  • TICSPro_TCP.py refactored into a more complete ti_ticspro package to facilitate startup options. See C:\Program Files(x86)\Texas Instruments\TICS Pro\ti_ticspro\readme.md after installation.
  • Startup options can be specified using the --settings flag when invoking TICS Pro.exe.
  • New APIs for USB I/O interfacing and log options
  • Substantial improvements to LMK05318B wizard, LMK5B and LMK5C profile families

Known Issues

  • LMK5B and LMK5C family - In some cases, "Assign Selected VCO Settings to Device" and "Apply Output Clock Settings to Device" may need to be pressed twice for certain cascaded configurations to display correctly
  • LMK05318 - In some cases, it is necessary to press "Calculate Frequency Plan" twice for correct VCO2 frequency. This issue is resolved in LMK05318B GUI.
  • Burst mode page looping requires long delays to halt, and halting may crash the GUI. If possible, do not loop in burst mode.
  • User Controls page can sometimes become desynchronized from Raw Registers and other pages. Refer to Raw Registers or other pages for correct values. Saving/Loading and Import/Export of register data is unaffected, and register data will still be written to and read from connected devices correctly.
