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
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.
