LMK04828: STATUS_LD Doesn't Asset 1

Kazuki Itoh

Part Number: LMK04828
Other Parts Discussed in Thread: CODELOADER

Hi team,

My customer is trying to configure PLL with CodeLoader 4 base off of the manual p.49 9.5.1.

He has input 0x171 to 0xAA and 0x172 to 0x02.

However, STATUS_LD doesn't assert to 1.

The PLL configured frequency waveform is confrimed by the customer.

Could you please help him debug the issue?

Do we have helpful app note for register value setting or setting procedure?

Regards,

Itoh

    Hello Itoh,

    I would suggest customer use the TICS Pro GUI control software as this is supported with newer updates.

    The Status_LD1 pin are also default open drain, so please ensure the settings in Register 0x15F [2:0] are correct for your termination.

    Regards,
