HMC996LP4E Power-up sequence

Hello,

I received an inquiry about power-up sequence of HMC996LP4E from our customer.

According to the datasheet, we should set Vctrl to -4.5V, and then adjust Vgg1, 2. In this case, how about Vdd1, 2?

Could you please advise me a recommended sequence? I couldn't fine an example of HMC996 or other products having Vctrl pin on AN-1363.

Best regards,

Akira

    Thank you for your answer.

    I have additional question. Does HMC996 has damaged by the following sequence?

     1. Vgg(-2V)         Vctrl            Vdd                   VggIdq 120mA

     2. Vgg(-2V)         Vdd             Vctrl                 VggIdq 120mA

     3. Vgg(-2V)            Vdd               VggIdq 120mA                       Vctrl

    Thanks & Regards,
