CDCE913: Power-up sequence

Part Number: CDCE913

Hi Team,

I found a power-up sequence on the datasheet.

However, details of the power-up sequence are not written in the data sheet.

I would like to know the details of power-up sequence.

What is the power-on sequence specification when VDD = 1.8 V and VDDOUT = 3.3 V?

Best Regards,

Kenji

    Two options are:

    Option #1
    1. Ramp VDD to 1.8V.
    2. Ramp VDDOUT to 3.3V.

    Option #2
    1. Ramp VDDOUT to 3.3V while VDD = 0V (not floated).
    2. Ramp VDD to 1.8V.

    There is no timing/delay requirement between the VDD and VDDOUT ramps.
