This document will explain voltage specifications, recommend solutions supplying consistent power, suggest validation techniques ensure robust 3.3V Pentium processor-based desktop server systems. (Voltage Regulated Extension) components have stricter supply voltage specifications than standard components, such VRE-based designs bring additional challenges power regulation. Although this document focuses designs, system design voltage measurement concepts also apply designs standard components. This document contains five sections: Chapter discusses standard specifications. standard voltage ranges have been adjusted C2-step subsequent processors. These changes reflected chapter (and entire document). Chapter also gives overview some important system design voltage measurement considerations associated with components. consequences specification violations also discussed. Chapter deals with power supply regulation. contains power implementation recommendations ensure robust system design. addition, this chapter contains detailed cost bulk high speed decoupling recommendations Socket Socket standard 3.3V designs. Chapter explains proper measurement techniques verify that systems meet their respective voltage specifications. These measurement techniques apply Pentium processors.

Since specification stricter requirement than standard voltage specification, VRE-based systems very sensitive voltage supply noise transients. overshoot undershoot beyond voltage range measurement bandwidth 20MHz) permitted. transient excursion beyond specified voltage range result unstable system behavior. Note that socket type measuring techniques also specified should followed ensure consistent accurate measurements. Complete S-Specs, availability Pentium processor family found latest Pentium processor stepping information Pentium Processor Specification Update (Order Number 242480). complete specifications shown above must ensure robust VRE-based platform. measurements must made guaranteed back motherboard socket pins. voltage specifications assume oscilloscope measurement bandwidth 20MHz.

Note that standard voltage range encompasses range, hence standard parts will operate systems.

Supply Voltage Range
components allow less transient tolerance than standard components. compensate smaller transient tolerance, VRE-based platforms must accurate voltage regulators adequate local decoupling capacitors. During worst-case transient conditions (transition into Stop Grant Mode Halt Power Down Mode), current supplied processor change several amperes tens
nanoseconds (Appendix provides information about obtaining simulation models accurately determining current change). Since power supply units voltage regulators best respond time frame order milliseconds, bulk decoupling capacitors required current reservoirs until power supply unit voltage regulators regulate load. high operation speed internal core Pentium processor, high frequency capacitors also required filter excessive noise components. Failure provide adequate power regulation during this transition result undershoot overshoot beyond voltage specifications processor.

Violating specifications undershooting overshooting voltage range will result unreliable unstable behavior. consequences voltage specification violations explained next section. Chapter will recommend techniques providing accurate regulation proper decoupling ensure robust VRE-based platform.
2.3. 2.2. Typical Appication Behavior
Voltage Specification Violations
Poorly designed desktop server systems will violate specifications during normal operation. unusual application instruction cause large current spikes from clock cycle clock cycle. Figure shows rapid fluctuations system power during execution BAPCo93* benchmark trace (BAPCo93 system benchmark used measuring system performance). These quick transitions current occur shorter time frame than that which power supply unit voltage regulator able respond. Worst-case transients occur during power management. Figure shows oscilloscope trace system leaving low-power Stop Grant State (via deassertion STPCLK#). supply voltage "droops" effects (see section 3.4), because voltage regulator cannot respond quickly enough large, instantaneous change current. Droops surges also occur systems with proper decoupling, lesser extent. system
Overshooting voltage specification cause certain signals violate their Minimum Valid Delay timing specifications. This timing violation will turn lead failure system. Excessive sustained overshooting also cause electron related effects which compromise reliability part. Undershooting causes reduction performance component, also lead timing related failures. processor will function properly correct clock frequency. effects undershooting aggravated improper cooling mechanisms. Extensive probing experiments show that high frequency overshooting undershooting voltage specification filtered processor's package parasitics, accounted during testing processor. result, recommended oscilloscope measurement bandwidth been adjusted 20MHz (see section details).

Until traditional power supply units with 3.3V outputs widely available, supplying power 3.3V Pentium processor requires 5V-to-3.3V voltage regulator. addition, robust local decoupling must provided accommodate transition from low-power modes. important select components accurate possible. platform based inaccurate power supply unit must compensated with more accurate regulator extra local decoupling. Similarly, platform based inaccurate regulator requires accurate supporting components additional decoupling capacitors.
specification allows total voltage budget 200mV. important understand voltage budget must include deviation voltage regulator, inaccuracy supporting components, other non-ideal behavior real components. When designing VRE-based platform, these factors must subtracted from
total budget. remaining allowance should targeted when measuring voltage transient. hence important select accurate voltage regulators precise support components allow maximum voltage transients.

Selecting Accurate Power Supply Unit

Sufficient decoupling must provided between power supply unit voltage regulator minimize noise. disturbance power supply unit exceed specification logic devices decoupling capacitance insufficient.
power supply unit must provide minimum setpoint equal higher than minimum input voltage required regulator. Off-the-shelf power supply units with accuracy specification meet typical 4.75V requirement most regulators. However, power supply unit with accuracy provide setpoint 4.5V fail minimum input requirement. Similarly, accurate power supply unit also fail voltage regulator

3.2. Selecting Accurate Voltage Regulator
There types voltage regulators: switching linear. Switching regulators provide power pulsing voltages currents load, thus resulting lower heat dissipation higher efficiency. Switching regulators however generally more expensive require more supporting components than linear regulators. Linear regulators essentially voltage dividers provide power "dividing down" inputs 3.3V outputs. Linear regulators dissipate more power, less expensive typically require only additional (feedback) resistors. Unless system strict thermal requirements, linear regulators generally suited high-volume designs. Both types regulators meet voltage range they have accurate outputs precise supporting components. Table below compares types voltage regulators:

inaccurate regulator leaves little room transient tolerance. example, specifications allow voltage regulator solution deviate only percent (3.4V 3.6V) from desired regulator setpoint 3.5V. Static specifications such line regulation, temperature drift, initial setpoint must held transient permitted all. Table recommends voltage regulator module accuracy required ensure robust VREbased platform. There direct tradeoffs between accuracy regulator amount local decoupling. Using inaccurate regulator requires more accurate dividing resistors more decoupling. Conversely, using high-ESR, quick-aging capacitors necessitates accurate regulators. next section recommends bulk high-speed decoupling required ensure robust VRE-based platform. recommendations were based extensive simulations empirical measurements.

High frequency capacitors between power ground planes near processor, required filter these high frequency noise components. Since inductive effects circuit board traces component leads become more critical higher frequencies, critical place high frequency capacitors near possible processor, using short traces minimize inductance.
