LMX2582EVM
LMX2582EVM 具有集成 VCO 的高性能、宽带频率 PLLatinum RF 合成器
LMX2582EVM
概述
此评估模块用于 LMX2582,后者可输出极高频率的信号,并拥有业内先进的相位噪声水平。集成式 VCO 可尽可能减少要设计的分立式外部元件。PCB 经过性能优化,同时设计为能够轻松定制环路滤波器。采用 LED 设计,用于快速目视检查 PLL 锁定状态。借助板载振荡器,设置过程中只需要一个 3.3V 电源和一个附带的 USB2ANY 模块。此外,软件非常简单,提供直观且易用的 GUI。
特性
- 相位噪声极低的输出(20 至 5500MHz)
- 可锁定至 5 至 1400MHz 的输入信号
- 单个 3.3V 电源
- 两路差动输出,具有可编程的输出功率
- 此 EVM 具有用于合成器的完整电路,经过性能优化和测试,并包括一个 USB 编程模块
- LMX2582EVM
- USB2ANY

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NOTE: v1.7.7.8 was withdrawn due to the installer being built with an older version of several profiles.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