Power-up sequence for LTC6951

Category: Datasheet/Specs
Product Number: LTC6951

Hello,

I have a question about power-up sequence of LTC6951 from our customer.
I think that LTC6951 does not need a power-up sequence because I can not find a dependence on supply voltages in the table of ABSOLUTE MAXIMUM RATINGS.
Is my understanding correct?

Best regards,

  • Hi y_suzuki,

    Yes. There is no specific power-up sequence for the LTC6951. If both power cannot be supplied simultaneously, I would recommend supplying the 3.3V first before the 5V. This is to power up the digital core first before the VCO. Also, I would recommend powering up the part first before supplying the reference clock.

    Best regards,
