LMK61E2EVM
LMK61E2EVM 超低ジッタ、プログラマブル・オシレータ評価モジュール
LMK61E2EVM
概要
The LMK61E2EVM evaluation modules provides a complete platform to evaluate the 90-fs RMS jitter performance and configurability of the Texas Instruments LMK61E2 Ultra-Low Jitter Programmable Differential Oscillator with integrated EEPROM and frequency margining capabilities.
The LMK61E2EVM can be used as a high performance clock source for jitter criticial applications and can easily be customized to any user desired frequency and output format. 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 LMK61E2’s differential clock output for interfacing to test equipment or reference boards using commercially available coaxial cables, adapters, or baluns (not included).
特長
- Ultra low jitter differential 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 LMK03328 registers and EEPROM
- LMK61E2EVM
- 3-ft. USB cable, Q362-ND

リリース情報
NOTE: v1.7.7.8 was withdrawn due to the installer being built with an older version of several profiles. v1.7.7.9 includes the correct files, and is otherwise identical to v1.7.7.8.
Bug Fixes
- Start Page: dimming improvements for unused input references, force FB config 1 only and require manual copying for FB config 2
- Validation Page: DPLL LOFL validation registers for FB2 are programmed for cases where FB2 is used
- ZDM Page: Added relative time calculations for DPLLx_PH_OFFSET
- Programming Page: Added DPLL loop filter register generator, clearly indicate ROM-only registers for post-EEPROM boot sequence
- LMK5B12212 will now calculate loop filter values
- LMK5B12212 and LMK5C12212A "Read Status" and "Read RO Regs" buttons fixed
- LMK5B12212 and LMK5C12212A corrected PLL1 VCO post-divider frequency on OUT0&1, OUT2&3 pages
- Improved accuracy of frequency error warnings
- Frequency Planner: OUT0/OUT1 CMOS and LDO voltage are now correctly set, REFx for OUT0 or OUT1 is now correctly set
- ZDM configuration now fails more gracefully for unsupported non-integer input/output attempts
Known Issues
- NEW: 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
- 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.
