3.10. M20K Embedded Memory Block Input Clock Quality Requirement

A stable input clock to the selected memory block is important to ensure the success of your Intel Agilex® 7 Embedded Memory designs.
  • Ensure the input clocks are clean and stable before configuring your device. The use of PLL-generated clocks for a clean clock source is always recommended.
  • Ensure a synchronous clock switchover between clock sources by using the clock gating features available in Embedded Memory or Clock Control IP.
  • When reconfiguring the clock source in user mode, it is recommended to disable the clock enable port until the input clock is clean and stable.
