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.
Thank you for your answer.
I have additional question. Does HMC996 has damaged by the following sequence?
1. Vgg(-2V) → Vctrl → Vdd → Vgg（Idq 120mA）
2. Vgg(-2V) → Vdd → Vctrl → Vgg（Idq 120mA）
3. Vgg(-2V) → Vdd → Vgg（Idq 120mA） → Vctrl
Thanks & Regards,
