LMK61E0MEVM
LMK61E0M 超低ジッタ・プログラマブル・オシレータの評価モジュール
LMK61E0MEVM
概要
The LMK61E0MEVM evaluation modules provides a complete platform to evaluate the jitter performance and configurability of the Texas Instruments LMK61E0M Ultra-Low Jitter Programmable Oscillator with integrated EEPROM and extended frequency margining capabilities.
The LMK61E0MEVM can be used as a high performance clock source for jitter critical applications and can easily be customized to any user desired frequency. The onboard USB to I2C interface allows for device configuration via a software graphical user interface (GUI) and requires no external input or power for device operation. The edge-launch SMA ports provide access to the LMK61E0M’s dual LVCMOS clock outputs for interfacing to test equipment or reference boards using commercially available coaxial cables, adapters, or baluns (not included).
特長
- Ultra low jitter dual output LVCMOS clock generation
- Powered over USB or externally (SMA connector)
- Onboard USB to I2C interface
- Coarse and Fine Frequency margining
- GUI platform for full access to registers and EEPROM
- 3-ft. USB cable, Q362-ND

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.
