Part Number: LMK04828

Hello,

 

Although LMK04828 has many kind of Vcc rails, are those Vcc rails can be powered up in any order?

 

Best regards,

    Hello Hirano-san,

    The VCC rails may be powered up in any order.

    Once the VCC rails are powered up and stable, the device should be reset by writing 1 to the RESET register (R0[7]) or by asserting HIGH signal on the reset pin, and then all registers should be programmed. The datasheet recommended programming sequence (section 9.5.1) is a good example to follow.

    Regards,
