Hello,
I have a question about AD9545/PCBZ from our customer.
On the AD9545/PCB, the VDD pins are connected through 0.1uF capacitor, Z20x filter from VDD_DUT.
Usually, I think the 0.1uF capacitor is placed near the VDD pins, and the filter is placed on the front of the 0.1uF.
Why is the 0.1uF capacitor placed in front of the filter on the AD9545/PCB?
Best regards,
