Hello,

I am using AD9548/PCBZ.

I have a question about the output mode of the IRQ pin.

 

When IRQ pin mode= CMOS,active high.
when the event occurs(ex.Freq locked),I think that the IRQ pin is set to a Logic 1.

 

Also,When IRQ pin mode= CMOS,active low.
when the event occurs,the IRQ pin is set to a Logic 0.

Is this correct?.

It would be greatly appreciated if advice could be gotten.

Best Regards,
Kou
