    About the power domain diagram of EZ-USB FX 3

    ryuji_shimoda_3660866

      I am currently designing and reviewing with CYUSB 3014
      Application note AN 70707
      001-86523_AN 70707_EZ-SB_R_FX 3 _TM_FX 3 S _ TM_ Hardware_Design_ Guidelines _ and _ Schematic_Checklist_Japanese.pdf
      Data sheet
      CYUSB 3014 (EN) _ 001 - 79232. Pdf
      , The following difference is found in the power domain diagram of EZ - USB FX 3

      · U3TXVDDQ Pin does not have corresponding PIN in CYUSB 3014 data sheet
      ※ 2 PIN exists for U3RXVDDQ. (A 2 / B 5)

      · Does U3VSS being pull-down processed correspond to the data sheet U3VSSQ of CYUSB 3014?

      For the difference between the two points, what kind of terminal processing should we do if it is replaced by 4P in Figure 1 of application note AN 70707?
