LMK61E2EVM
LMK61E2EVM 超低抖动可编程振荡器评估模块
LMK61E2EVM
概述
LMK61E2EVM 评估模块提供了一个完整平台来评估具有集成式 EEPROM 和频率容限功能的德州仪器 (TI) LMK61E2 超低抖动可编程差动振荡器的 90fs RMS 抖动性能和可配置性。
LMK61E2EVM 可以用作抖动关键型应用的高性能时钟源,且可以轻松定制为用户期望的任何频率和输出格式。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,且无需提供外部输入或电源即可运行器件。边缘发射 SMA 端口可用于访问 LMK61E2 的差分时钟输出,从而使用市售同轴电缆、适配器或平衡-非平衡变压器(未附带)连接到测试设备或参考板。

发布信息
Added
- LMK5C23208A
Improvements
- TCP server returns error descriptions
- TICSPro_TCP.py updated for python ≥ 3.10. Remove type annotations if backward compatibility with older python versions is required.
- LMK5B/5C:
- Warn when GPIOx selects REFx monitor, but REFx is not programmed
- Relative calculation of DPLLx_PH_OFFSET value
- Added fields and improved frequency planning for 1-PPS outputs
- PLLx_RDIV_MUX_SEL only sets recommended values when dropdown is changed; no longer changed by DPLL loop filter calculation or TCS file load
- Advanced Options checkbox added on Getting Started page
- GPIOx descriptions updated for accuracy
- LMK5B12212, LMK5C12212A:
- New step added to Start Page process to reduce current consumption and noise
- SRAM sequence EEPROM generation sets optimized values from new step in Start Page process
- LMK5B33414, LMK5C33414A:
- Simplified programming sequence by combining writes for the output divider synchronization sequence generator
Bug Fixes
- LMK5B12212, LMK5C12212A:
- Some controls which were not register-backed have been updated to be register-backed.
- LMK5B33414, LMK5C33414A:
- Fixed "Set SYNC Enable" buttons on "SYNC/SYSREF/1-PPS" page
Known Issues
- 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
- 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.
