Agilex 7 with LTM4700 PMBus-Compliant Voltage Regulator

I'm developing a platform based on the Agilex 7: AGFB008R24C2E2V
and since this chip uses Smart VID I'm looking for a power controller that would implement this function.
I would like to use LTM4700 since it is most suitable for my design, and I see that it support Smart VID PMBUS.
But this chip is not on the list of supported ones. FPGA SmartVID | Altera 

Table 2. Recommended PMBus-Compliant Voltage Regulator

I would like to understand if I can use LTM4700

I am concerned about the phrase : 

  • If the voltage regulator is not properly selected and implemented, the device configuration will fail, and likely result in a costly board spin.

 

That’s why I’m asking here:

Can I safely use LTM4700 for SmartVID on Agilex 7 (AGFB008R24C2E2V)?

If so, do I simply select a similar regulator like LTM4677 in Quartus to activate SmartVID, assuming the PMBus address and protocol are correct?

Any confirmation or advice would be greatly appreciated.

Thanks in advance!

    Hello, 

     

    Sorry for late replying you. From our experience supporting worldwide customers, I would like to advice please dont use devices that is not listed as the supported/tested devices. If you are running your project on tight schedule, please use the device in the supported list, so your development will be smooth. 

     

    For the devices which is not in the supported list, the development will require engineering team to support in order to enable it, and this will take longer time than expected. 

     

    regards,
