LMK05028 网络时钟发生器和同步器评估模块
LMK05028EVM
概述
LMK05028EVM 是一款用于评估 LMK05028 网络时钟发生器和同步器的评估模块。该 EVM 可用于器件评估、合规性测试和系统原型设计。
LMK05028 集成了两个具有可编程带宽的数字锁相环 (DPLL),用于实现输入的漂移和抖动衰减。该 EVM 包含针对时钟输入、振荡器输入和时钟输出的 SMA 连接器,以便连接到 50Ω 测试设备。通过板载 XO 和 TCXO 选项,可在自由运行、锁定或保持模式下评估 LMK05028。通过板载 USB 微控制器 (MCU) 接口,可在 PC 上使用 TI 的 TICS Pro 软件图形用户界面 (GUI) 来配置该 EVM。TICS Pro 可用于对 LMK05028 寄存器进行编程并将相应设置保存在片上 EEPROM 中,从而支持自定义的通电时钟配置。
特性
- 两个具有可编程带宽的 DPLL 以及用于实现频率转换的模拟 PLL
- 4 个时钟输入,可支持无中断切换和保持
- 8 个差分输出时钟或 16 个 LVCMOS 输出时钟,或者二者的组合
- 通过片上 EEPROM 来支持自定义的启动时钟配置
- 灵活的振荡器选项:板载 XO 和 TCXO 或外部 SMA 输入
- USB MCU 接口,用于通过 TICS Pro GUI 进行 I2C/SPI 和 GPIO 引脚控制
3 英尺微型 USB 电缆 (MPN 3021003-03)

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NOTE: v1.7.7.8 was withdrawn due to the installer being built with an older version of several profiles.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.
