Smartvid Feature Implementation In Intel Agilex Devices - Intel Agilex User Manual

The SmartVID feature allows a power regulator to provide the Intel Agilex device with
V and V
CC
grade. When the SmartVID feature is used:
1. Intel Agilex devices are initially powered up to a nominal voltage level of the
respective power grade for both V
2. After the SmartVID value in the Intel Agilex device is determined and propagated
to the external voltage regulator, both the V
based on the SmartVID value.

5.1.1. SmartVID Feature Implementation in Intel Agilex Devices

Devices supporting the SmartVID feature have a SmartVID value programmed into a
fuse block during device manufacturing. The SmartVID value represents a voltage
level in the range of 0.6 V to 1.0 V. Each device has its own specific SmartVID value.
The SmartVID value is sent to the external regulator or system power controller
through the PMBus interface. Upon receiving the SmartVID value, an adjustable
regulator tunes the V
SmartVID value.
Intel Agilex devices perform the SmartVID setup in the early stage of the
configuration process. The SmartVID process will continue to monitor the V
voltage rails in user mode. The Power Manager monitors the temperature and adjusts
the voltage when required. For more information, refer to the Temperature
Compensation section.

When the system is required to support the CvP functionality and meet the PCI Express*
(PCIe*) link-up timing budget during the initial power up, the minimum ramp time is 10
mV/60 µs.
