LMX2594EVM: Confirm if Reference Pro board can be disconnected after PLL has been programmed

Part Number: LMX2594EVM

Hi Team,

I would like to confirm if after the PLL has been programmed, can the Reference Pro board be disconnected to LMX2594EVM?
Will the PLL retain its settings?

This is the question from our customer before buying this EVM.

Thanks,

Jonathan

    Hi Jonathan,

    Yes, the hardware is design in the way that the CE pin of the chip is pull-high by default. After programming, you can remove the programming cable without disturbing the chip. 

    You also have the option to control the CE pin by software with a few resistors rework.
