Part Number: LMK03328EVM

Dear Technical Support Team,

I have a question about schematic of LMK03328EVM.

LABEL PINS of Jumper 3(J3) shows "1=3.3V".

According to table 2 of datasheet ,this pin is for 5V.

Is it typo? 

Best Regards,

ttd

    Hi ttd,

    The header J3 is an alternative power connector to J1 and J2. If you use the onboard regulators, you can supply 5V to EXTVDD and EXTVDDO. If you do not use the onboard regulators, then please apply 3.3V to EXTVDD and 1.8V / 2.5V / 3.3V to EXTVDDO.

    Kind regards,
    Lane
