Could you please advise me power-up sequence (Vdd, Vdd1 and Vss) of HMC1019A? Or don'e we have to care about that for HMC1019A?
The ideal power-up sequence for the HMC1019A is as below. The power-down sequence is the reverse of the power-up sequence.1. Connect the ground reference.
2. Power up VDD and VSS. The relative order is not important.3. Power up the digital control inputs. The relative order of the logic control inputs is not important. However,powering the digital control inputs before the VDD supplycan inadvertently forward bias and damage the internal ESD protection structures.4. Apply an RF input signal.
Could you please support my question?
Thanks & Regards,
Thank you for you answer.
