Original question:

LMK04806: are program registers stored between power cycles?

Part Number: LMK04806

The configuration register failed probabilistically after LMK04806 was powered on.Read back the register, the result is all FFFFFF.The same configuration of the register can be successfully reconfigured without power dowm.The LMK04806's power supply and reference clock are stable until the registers are configured.What is the next step in locating the cause of the problem?

    Hello Xianhua,

    I'm not sure I fully understand your question.

    The LMK04806 does not have non volatile memory, so any settings are lost after power down and must be re-programmed.

    Also, you need to ensure the pin you are performing readback is configured for readback.
