66AK2H14 Core Power Supply(CVDD)

Other Parts Discussed in Thread: UCD74120, 66AK2H14

Hello,

 
 I am using DSP+ARM(66AK2H14) based Processor. In Reference Schematics(ADVANTAC),Core Supply CVDD used Separate Power Driver(UCD74120)for DSP & ARM Core Power Supply Using two Smart Refelx. Finally, both Power Driver ORed to Single net(CVDD). How is Phase tolerated from Both Ouput. Why they are using two drivers ?

In our Design, only one Power Driver(UCD74120) used for CVDD using one smart reflex. Our Current requirement is 22A(Max). Can we connect like this?

Kindly give your suggestion as soon as possible.

Regards.
