All application notes and evaluation boards I could find are using the larger 121 ball package(0.8mm pitch) with more convenient placing of the USB signal pins. Is there a reference design or design recommendations available for routing out the signals on the smaller 131 ball WLCSP (0.4mm pitch) of the FX3 (CYUSB3014-FBXIT and CYUSB3014-FBXCT) as the pinout for the USB signals is quite different and the fanout is more difficult due to the finer pitch?
Thanks in advance.
We do not have any reference designs as of now wiith WLCSP. Please contact the Tech Support for design recommendcations with WLCSP
