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

TICS Pro 1.7.7.9 Release Notes
TICS Pro 1.7.7.9 Software Manifest
发布信息
NOTE: v1.7.7.8 was withdrawn due to the installer being built with an older version of several profiles.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.
