document is to define the electrical, thermal and mechanical design specifications for
VRM/EVRD 11.0.
VRM – The voltage regulator module (VRM) designation in this document refers to a
voltage regulator that is plugged into a baseboard via a connector or soldered in with
signal and power leads, where the baseboard is designed to support more than one
processor. VRM output requirements in this document are intended to match the needs
of a set of microprocessors.
voltage regulator that is plugged into a baseboard via a connector or soldered in with
signal and power leads, where the baseboard is designed to support more than one
processor. VRM output requirements in this document are intended to match the needs
of a set of microprocessors.
EVRD – The enterprise voltage regulator down (EVRD) designation in this document
refers to a voltage regulator that is permanently embedded on a baseboard. The EVRD
output requirements in this document are intended to match the needs of a set of
microprocessors. EVRD designs are only required to meet the specifications of a
specific baseboard and thus must meet the specifications of all the processors
supported by that baseboard.

‘1’ – In this document, refers to a high voltage level (V
OH
and V
IH
).
‘0’ – In this document, refers to a low voltage level (V
OL
and V
IL
).
‘X’ – In this document, refers to a high or low voltage level (Don’t Care).
‘#’ – Symbol after a signal name in this document, refers to an active low signal,
indicating that a signal is in the asserted state when driven to a low level.
