The datasheet for the QPC8010Q (Rev G) specifies the “Power-Up / Power-Down Sequence and Operational Controls.” What are the potential consequences of not adhering to these guidelines?
Is there a risk of causing fatal damage to the hardware, or are these sequences primarily indicated to prevent the formation of unintended signal paths?
Could you explain the reasons why sequence control is necessary?
Hello. If power-up/power down sequencing is not followed, there could be an impact to long term reliability.
Hello.
Thank you for your reply.
I understand the necessity of the power on/off sequence.
I assume that the sequence requirement before and after the CTRL pin control of Switching Ports is for a different reason, but what kind of problems will occur if the switching port sequence requirement is not observed?
Hello. There is a “hot switching” specification in the “Absolute Maximum Ratings” table that allows for a maximum RF input level of 20 dBm when RF signal is applied and the RF ports are switched.
Hello.
I understand from the “hot switching” specification that it is permissible to switch the RF port while a maximum of 20 dBm RF signal is applied.
Thank you for your support.
