LMX2694EPEVM
15-GHz 宽带射频合成器评估模块
LMX2694EPEVM
概述
此评估模块适用于 LMX2694-EP 支持扩展温度的 15GHz 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。LMX2694-EP 允许设计人员同步多个器件实例的输出。
特性
- 15GHz 直接 VCO 输出
- 在 8GHz 载波下具有 54fs RMS 抖动(100Hz 至 100MHz)
- 跨多个器件实现输出相位同步
- SYSREF 支持
- 工作温度范围:-55°C 至 +115°C
- 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

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NOTE: v1.7.7.8 was withdrawn due to the installer being built with an older version of several profiles.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