Overview

This evaluation module is for the LMX2595, which is the first PLL with integrated VCO in industry to get fundamental VCO output up to 15 GHz and up to 20 GHz with a doubler. The industry leading PLL FOM is -236 dBc/Hz with 1/f of -129 dBc/Hz. This device supports the 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 9 GHz carrier frequency. By providing a SYNC signal, the user can synchronize the output phase across multiple LMX2595 devices. LMX2595 can also generate a frequency ramp which can be demonstrated in this evaluation module. With an on-board oscillator, setup process only requires a 3.3V power supply and an included Refernce Pro module (For SPI Programming interface). The software is simple, with an intuitive and user friendly GUI.

Features
  • 10-MHz to 20-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
  • This EVM has the complete circuit for the synthesizer, optimized and tested for performance, and includes a USB programming module

  • Reference Pro
  • USB2ANY

Added Features

LMK5Bxxyyy, LMK5Cxxyyy

  • Warnings and errors improved, particularly corrective suggestions
  • REFx_FREQ=0 automatically disables DPLL reference input selection for that input
  • Input validation enabled and disabled by start page settings, including 1PPS
  • APLL reference selection moved to Step 5, just before clock output definition
  • Quick-set multiple outputs to the same settings on frequency planner
  • BAW VCO allows some ppm deviation
  • Force SYSREF option on OUT0/1
  • Expose DPLLx_LCK_TIMER field
  • Match LMK05318B EEPROM page design
  • .EPR export option
  • EEPROM SRAM programming generation support
  • For complete changelist, see release notes

LMK3H0102

  • Configuration search tool
  • Wizard: voltage selection option

Bug Fixes

  • LMK04832-SP, LMK04832-SEP, LMK04714-Q1, LMK04368-EP - PD_FIN0 corrected to FIN0_PD
  • LMK3H0102 - Several wizard bugfixes

Known Issues

  • LMK5C33216 - When cascading from VCO3 to DPLL input, the divide value must manually be entered into DPLLx_REF5_RDIV as ( VCO3 output frequency / DPLLx TDC frequency )
  • 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.
