Part Number: LMK03328

Hello Team,

Is it possible to have input signal on PRIREF_P/PRIREF_N or on SECREF_P/SECREF_N without powering the device?

thanks and regards

Hello Adrian,

The input voltage for clock/logic inputs must not exceed Vdd + 0.3 V (as given in the Absolute Maximum Ratings table) to avoid permanent damage to the chip.
