  • RE: C6670's CVDD pin is short to GND

    Resolved
    Hi Tom, Thanks for your replies. 1. I had test one known good board(not the EVM, just another), the resistance between C6670's CVDD and VSS is around 8 Ohm. But on my board, I got the resistance value that is less than 1 Ohm with the same test equipment…

    Resolved
    UCD9222 does not come with a default configuration, it can be used with a wide variety of applications. The Fusion Digital Power Designer (FDPD) software is used to create the configuration for the UCD9222 controller. There are a number of methods…

  • RE: C6672 - Main PLL issue / power failure on target CPU

    Hi Tom, thanks for your insight! We will do some additional testing / measuring concerning CVDD/CVDD1 and AVDDA1/2/3 to rule out any voltage drops / current starvation. In general, the design is largely based on the C6678 EVM kit, so we're using…
