LMK1C1104: Clock buffer failing voltage derating

Part Number: LMK1C1104


The clock buffer LMK1C1104DQFT has a absolute maximum rating of 3.6V on VDD pin. For 10% derating, i.e at 90% rated voltage operation,this IC fails.

  3.3V/3.6V = 0.916 = 91.6%.Kindly let us know if the absolute maximum voltage for VDD is 3.6V or higher.

  • Hi Premalatha,

    Recommend supply condition for the device are for VDD +/- 5%. Absolute maximum rating in the datasheet is defined for permanent damage to device.  

    Do you expect your supply condition to be equal or  above +/-10%? If so, It would result in degrading of the device or permanent damage.
