PECI DC Characteristics
The PECI interface operates at a nominal voltage set by Vcc1p05_PROC. The set of DC electrical specifications shown in the following table is used with devices normally operating from a Vcc1P05_PROC interface supply.
Vcc1p05_PROC nominal levels will vary between processor families. All PECI devices will operate at the Vcc1p05_PROC level determined by the processor installed in the system.
Input Device Hysteresis
The input buffers in both client and host models should use a Schmitt-triggered input design for improved noise immunity. Use the following figure as a guide for input buffer design.
