LM65645EVM: LM65645

Part Number: LM65645EVM
Other Parts Discussed in Thread: LM65645

Tool/software:

External synchronization usually does not work!

To activate it, it is necessary to turn it off and on via the EN input signal,

which also does not always allow external synchronization.

Replacing the component "LM65645" on the Demo board did not help.

  • Hi,

    Can you confirm if the signal you are giving externally meets the width and level criteria given in section 7.3.3.1 of the datasheet? You will find the values of the parameters mentioned there in the Electrical characteristics table.

    Have you made any changes to the EVM? Also, what frequency are you trying to force and what is the RT pin connected to?

    Regards,
