About connection line from V1P2 to VDD

Reference circuit diagram FX3_DVK_DEVICE_BOARD In the document

Although FB MPZ2012S601A is connected

Application note 001-86523_AN 70707_EZ-USB_R_FX3_TM_FX3S_TM_Hardware_Design_Guidelines_and_Schematic_Checklist_Japanese.pdf there is no description of the FB connection to the VDD line

Is FB necessary as the latest information to advance design? Is it unnecessary?

Ferrite Bead (FB) is needed for AVDD, U3TXVDD, U3RXVDD, and CVDD.

It is described at AN70707.

Regarding VDD, you do not need to connect FB. Which schematic have you seen?

Best regards,

It is highly probable that you are checking OBSOLETED schematic since that file is in "EZ-USB® FX3™ Development Kit (CYUSB3KIT-001) (OBSOLETE)".

You can refer to "SuperSpeed Explorer Kit Hardware Files" on CYUSB3KIT-003 web page instead of CYUSB3KIT-001.

I think FX3 with Type-C connector might be helpful for you.

We do not have a schematic like CYUSB3KIT-003 since we do not offer EVK for FX3 with Type-C.
