XIO2213BEVM Orcad files

This customer has an additional question: 

"The part comes in two different packages ZAJ (168 balls) and ZAY (167 balls, but physically larger).  Is there a recommended package?  That is, is one of them more readily available, or cheaper?  I see that the eval board uses the larger package (ZAY)."

Looking in the d/s, i don't see major differences in the pinouts, and there are no mech dwgs!  :(   

What are the purposes of the two package options?

Hello:  the customer has an additional question on the XIO2213B: 

>>>>

I am using 2 of the 3 ports in “Beta” mode and do not use the 3^rd port at all.  According to the datasheet, the VREG_PD pin when grounded enables the in-chip 3.3 V to 1.95 Volt regulator.  The literature further says that: “When using the internal regulator, the XIO2213B can support a maximum of 2-Beta and 1-DS connection simultaneously.” 

Since I am using only 2 ports in Beta mode, I think that I fall into the above category.

1)      Since I am using the internal regulator, I do not need to externally generate 1.95 V, is my understanding correct?

2)      Should I still provide decoupling capacitors to the following pins: DVDD_CORE (3 pins) and PLLVDD_CORE (1 pin)?

Hello George,

1) Correct, you do not need to externally supply 1.95V when VREG_PD is connected to ground.

2) Yes, it is recommended to keep the caps for noise filtering.

Regards.

any word on the package question?  thx

Hello George,

either package will have the same performance, regarding the cost and availability please send me an email to elias.villegas@ti.com and I can get you with the right person.
