LMX2820EVM
LMX2820 22.6-GHz 宽带射频合成器评估模块
LMX2820EVM
概述
此评估模块适用于 LMX2820 22.6GHz 宽带射频合成器。此合成器支持符合 JESD204B 标准的 SYSREF 信号缓冲和生成。LMX2820 允许设计人员同步多个器件实例的输出。
特性
- 22.6GHz 输出
- 在 6GHz 载波下具有 40fs RMS 抖动(10kHz 至 20MHz)
- 跨多个设备实现输出相位同步
- SYSREF 支持
- 支持高达 22.6GHz 的外部 VCO 输入
- 此评估模块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

Bug Fixes
- LMK05028 - bugfixes to frequency updates and DPLL coefficient script
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
- 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.
