LMK61E2EVM
LMK61E2EVM 超低抖动可编程振荡器评估模块
LMK61E2EVM
概述
LMK61E2EVM 评估模块可提供完整的平台,评估德州仪器 (TI) LMK61E2 超低抖动可编程差分振荡器的 90-fs RMS 抖动性能和可配置性,该器件具有集成式 EEPROM 和频率裕量功能。
LMK61E2EVM 可用作抖动关键型应用的高性能时钟源,且可轻松定制任何用户所需的频率和输出格式。借助板载的 USB 转 I2C 接口,可通过软件图形用户界面 (GUI) 进行器件配置,且无需外部输入或电源即可运行器件。边缘安装的 SMA 端口用于访问 LMK61E2 差分时钟输出,进而通过市面上出售的同轴电缆、适配器或平衡-非平衡变压器(需单独购买)对接至测试设备或参考板。
特性
- 超低抖动差分时钟发生

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.
