LMK5B33414EVM
适用于 LMK5B33414 具有 BAW VCO 的 14 路输出、3 个 DPLL 和 APLL 的网络同步器的评估模块
LMK5B33414EVM
概述
LMK5B33414 评估模块 (EVM) 是对 LMK5B33414 网络时钟发生器和同步器进行器件评估、合规性测试和系统原型设计的平台。
LMK5B33414 集成了三个模拟锁相环 (APLL) 和三个具有可编程环路带宽的数字 PLL (DPLL)。该 EVM 包含用于时钟输入、振荡器输入和时钟输出的超小型版本 A (SMA) 连接器,可将器件连接到 50Ω 测试设备。通过板载温度补偿晶体振荡器 (TCXO),可在自由运行、锁定或保持模式下评估 LMK5B33414。
通过板载 USB 微控制器 (MCU) 接口,可在 PC 上使用 TI 时钟和合成器 (TICS) 专业版软件 (TICSPRO-SW) 来配置 LMK5B33414EVM。TICSPRO-SW 可用于对 LMK5B33414 寄存器进行编程。
特性
- 三个具有可编程带宽的 DPLL 和三个可灵活生成时钟的分数 APLL
- DPLL 有四个基准输入,可支持无中断切换和保持
- 14 个输出时钟 - 由声体波 (BAW) 驱动的输出可实现低于 50fs 的均方根 (RMS) 相位抖动(12kHz 至 20MHz)
- 灵活的振荡器源 - 板载 TCXO,或其他晶体振荡器 (XO)、温度补偿晶体振荡器 (TCXO)、恒温晶体振荡器 (OCXO) 的几种类型之一,或外部 SMA 输入选项
- 用于定制启动时钟配置的片上电可擦除可编程只读存储器 (EEPROM)
- 3ft Mini-USB 电缆 (MPN 3021003-03)
AC/DC 和 DC/DC 转换器(集成 FET)

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NOTE: v1.7.7.8 was withdrawn due to the installer being built with an older version of several profiles.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