 Does 1SG085HN2F43E2LG must need to connect the PMBUS？

Is it necessary to connect pmbus pin only if tail is - V?

Hi , 

Does 1SG085HN2F43E2LG must need to connect the PMBUS？ >> Yes as per the recommendation,

Kindly find the explanation.

 Intel Stratix 10 devices will not configure or function correctly if the core voltage is driven by a non-PMBus compliant regulator with a fixed output voltage

Hi

我看了下这个文档，应该是-v的才必须接PMBUS，-L的应该可以不接对吧？

Hi Rxie ,

Kindly find the my reply below in details.

For Stratix 10 with support for SmartVID standard power ,you must connect the PWRMGT_SCT and PWRMGT_SDA connect to power management bus.

There are other opn in which the power line is fixed, that is L and X , in that there is no support for Smart VID , the power is fixed ,

Kindly find the reference in PCG : PAGE NO:28

If the OPN have L or x no support for SMART VID , so connection is not required , hope it clarifies
