      Clock and Timing
      31 March, 2025
      The AD9545 manual (pg 164) details that upon power up, you must wait to connect your reference inputs until after the board powers up, the power supply stabilizes, and 60ms have passed after VDD settles. I have the eval board, and this is fine for testing. I just power on …
