TUSB1210: VDD and VBat questions (CByp)

Part Number: TUSB1210


Hello E2E,

My customer is looking to use TUSB1210 with 3.3V tied to VBAT.  In this case they will tie VDD33 together.  Questions:

Is this the correct way to connect the device - shorting VBAT and VDD33 together?

Do they each need their own filter capacitor or will one do?

What Cbyp values should they use?  See table 8.3 and the Cbyp line.  The recommended value is 0.1uF, but  the range is set to 0.45uF to 6.5uF.  I am assuming that this means to use a 0.1uF cap + a larger bulk cap (say 2.2uF).

Please confirm

Thanks!

Russell
