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

Bug Fixes
- Fix locale issue causing floating point numbers to be parsed incorrectly in some locales
- Fix incorrect check for .NET Framework 4.8
- Stack trace include in error log when available
- Fix LMK05318B EEPROM export text to properly display "R157" instead of "R171"
- USB2ANY firmware revision update: v2.9.1.2
- If pin 77 of MSP430 was grounded, v2.9.1.1 firmware would not initialize I2C on the correct pins. This is corrected in v2.9.1.2
- Update affects Reference PRO, LMX1214, and LMX1906-SP evaluation modules
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.
最新情報
- Added LMX1214, LMX1906-SP
- USB2ANY firmware revision update: v2.9.1.2
