Worry!!! Question about UCD90120A

Other Parts Discussed in Thread: UCD90120A

The application of UCD90120A in my design as follow:
 

       The Datasheet of UCD90120A introduce three general device-configuration

programming options:


       Which way is suitable for my application? Option 3? FPGA can't communicate with it before the UCD90120A is configured. Because FPGA is not powered up.

        Whether I can as this?

       Connect the PMBus signals to a socket, then use a JTAG programmer to program the UCD90120A via PMbus.If OK,I want to know:

  1. Does TI have the JTAG programmer?
  2. What is the configuration file? Script file? Image file? Created by Fusion GUI?
