LMK05318BEVM
网络同步器时钟评估模块
LMK05318BEVM
概述
这是一款适用于 LMK05318B 网络同步器时钟器件的评估模块 (EVM)。
该 EVM 可在快速评估、合规性测试和系统原型设计中用作灵活的同步时钟源。SMA 端口可用于访问 LMK05318B 时钟输入和输出,以便连接到 50Ω 测试设备。该评估模块包含板载 XO 选项,但可采用各种 XO/TCXO/OCXO 封装对这些选项进行重新设计,或对其设置旁路以便使用外部 SMA 输入。该 EVM 提供一个基于 USB 的接口来访问 LMK05318B 的 I2C/SPI 总线和控制引脚。可使用 TICS PRO 软件 GUI 对 LMK05318B 的寄存器和 EEPROM 进行编程,以便存储自定义的启动时钟设置。
特性
- 一个具有可编程带宽的数字 PLL (DPLL) 和两个分数模拟 PLL (APLL),可实现灵活的时钟生成。
- DPLL 的两个基准输入,可支持无中断切换和保持
- 八个输出时钟,RMS 相位抖动为 50fs(12kHz 至 20MHz)
- 通过片上 EEPROM 来存储自定义的启动时钟配置
- 灵活的振荡器源:板载 XO 或外部 SMA 输入选项

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.
