Glossary of Terms and Acronyms
This section defines conventions and terminology used throughout this document.
Aggressor
A network that transmits a coupled signal to another network.
Any plane-split, void or cutout in a VCC or GND plane.
Assisted Gunning Transceiver Logic+
The front-side bus uses a bus technology called AGTL+, or Assisted Gunning Transceiver Logic. AGTL+ buffers are open- drain, and require pull-up resistors to provide the high logic level and termination. AGTL+ output buffers differ from GTL+ buffers with the addition of an active pMOS pull-up transistor to assist the pull-up resistors during the first clock of a low-to-high voltage transition.
Asynchronous GTL+ The processor does not utilize CMOS voltage levels on any
signals that connect to the processor. As a result, legacy input signals such as A20M#, IGNNE#, INIT#, LINT0/INTR, LINT1/ NMI, PWRGOOD, SMI#, SLP#, and STPCLK# utilize GTL+ input buffers. Legacy output signals (FERR# and IERR#) and non- AGTL+ signals (THERMTRIP# and PROCHOT#) also utilize GTL+ output buffers. All of these signals follow the same DC requirements as AGTL+ signals, however the outputs are not actively driven high (during a logical 0 to 1 transition) by the processor (the major difference between GTL+ and AGTL+). These signals do not have setup or hold time specifications in relation to BCLK[1:0], and are therefore referred to as "Asynchronous GTL+ Signals". However, all of the Asynchronous GTL+ signals are required to be asserted for at least two BCLKs in order for the processor to recognize them.
Bus Agent
A component or group of components that, when combined, represent a single load on the AGTL+ bus.
The reception on a victim network of a signal imposed by aggressor network(s) through inductive and capacitive coupling between the networks.
• Backward Crosstalk - Coupling that creates a signal in a victim network that travels in the opposite direction as the aggressor's signal.
• Forward Crosstalk - Coupling that creates a signal in a victim network that travels in the same direction as the aggressor's signal.
• Even Mode Crosstalk - Coupling from a signal or multiple aggressors when all the aggressors switch in the same direction that the victim is switching.
• Odd Mode Crosstalk - Coupling from a signal or multiple aggressors when all the aggressors switch in the opposite direction that the victim is switching.
Flight Time
Flight time is a term in the timing equation that includes the signal propagation delay, any effects the system has on the TCO of the driver, plus any adjustments to the signal at the receiver Intel® CoreTM 2 Duo processor with the Mobile Intel® 945GME Express Chipset Order Number: 317443-001US Intel® 945GME Express Chipset—About This Manual
needed to ensure the setup time of the receiver. More precisely, flight time is defined as: • The time difference between a signal at the input pin of a receiving agent crossing the switching voltage (adjusted to meet the receiver manufacturer's conditions required for AC timing specifications; i.e., ringback, etc.) and the output pin of the driving agent crossing the switching voltage when the driver is driving a test load used to specify the driver's AC timings.
• Maximum and Minimum Flight Time - Flight time variations are caused by many different parameters. The more obvious causes include variation of the board dielectric constant, changes in load condition, crosstalk, power noise, variation in termination resistance, and differences in I/O buffer performance as a function of temperature, voltage, and manufacturing process. Some less obvious causes include effects of Simultaneous Switching Output (SSO) and packaging effects.
• Maximum flight time is the largest acceptable flight time a network will experience under all conditions.
• Minimum flight time is the smallest acceptable flight time a network will experience under all conditions.
Infrared Data Assoc. The Infrared Data Association (IrDA) has outlined a specification
for serial communication between two devices via a bi- directional infrared data port. The 945GME platform has such a port and it is located on the rear of the platform between the two USB connectors.
The Intel Mobile Voltage Positioning specification for the Intel® Core™ 2 Duo Processor. It is a DC-DC converter module that supplies the required voltage and current to a single processor.
Inter-symbol interference is the effect of a previous signal (or transition) on the interconnect delay. For example, when a signal is transmitted down a line and the reflections due to the transition have not completely dissipated, the following data transition launched onto the bus is affected. ISI is dependent upon frequency, time delay of the line, and the reflection coefficient at the driver and receiver. ISI may impact both timing and signal integrity.
Media Expansion CardThe Media Expansion Card (MEC) provides digital display options
through the SDVO interface. The MEC card also incorporates The network is the trace of a Printed Circuit Board (PCB) that completes an electrical connection between two or more The maximum voltage observed for a signal at the device pad, measured with respect to VCC.
The electrical contact point of a semiconductor die to the package substrate. A pad is only observable in simulations.
The contact point of a component package to the traces on a substrate, such as the motherboard. Signal quality and timings may be measured at the pin.
Intel® CoreTM 2 Duo processor with the Mobile Intel® 945GME Express Chipset Order Number: 317443-001US About This Manual—Intel® 945GME Express Chipset
"Power-Good," "PWRGOOD," or "CPUPWRGOOD" (an active high signal) indicates that all of the system power supplies and clocks are stable. PWRGOOD should go active a predetermined time after system voltages are stable and should go inactive as soon as any of these voltages fail their specifications.
The voltage to which a signal changes after reaching its maximum absolute value. Ringback may be caused by reflections, driver oscillations, or other transmission line System Bus
The System Bus is the microprocessor bus of the processor.
Setup Window
The time between the beginning of Setup to Clock (TSU_MIN) and the arrival of a valid clock edge. This window may be different for each type of bus agent in the system. Simultaneous Switching Output
Simultaneous Switching Output (SSO) effects are differences in electrical timing parameters and degradation in signal quality caused by multiple signal outputs simultaneously switching voltage levels in the opposite direction from a single signal or in the same direction. These are called odd mode and even mode switching, respectively. This simultaneous switching of multiple outputs creates higher current swings that may cause additional propagation delay ("push-out") or a decrease in propagation delay ("pull-in"). These SSO effects may impact the setup and/ or hold times and are not always taken into account by simulations. System timing budgets should include margin for SSO effects.
The branch from the bus trunk terminating at the pad of an The main connection, excluding interconnect branches, from System Management Bus
A two-wire interface through which various system components may communicate.
The minimum voltage extending below VSS observed for a signal at the device pad.
VCC (CPU core)
VCC (CPU core) is the core power for the processor. The system bus is terminated to VCC (CPU core).
A network that receives a coupled crosstalk signal from another network is called the victim network.

Setting Up the Evaluation Board
Once the necessary hardware (described in has been gathered, follow the steps below to set up the Intel® 945GME Express Chipset evaluation board.
To locate items discussed in the procedure below, please refer to .
1. Create a safe work environment.
Ensure a static-free work environment before removing any components from their anti-static packaging. The evaluation board is susceptible to electrostatic discharge (ESD) damage, and such damage may cause product failure or unpredictable operation. A flame retardant work surface must also be used.
Because of this susceptibility, it is recommended that an ESD wrist strap be
used when handling the board.
2. Inspect the contents of your kit.
Check for damage that may have occurred during shipment. Contact your sales representative if any items are missing or damaged.
Since the board is not in a protective chassis, use caution when connecting
cables to this product.
Standby voltage is constantly applied to the board. Therefore, do not insert or
remove any hardware unless the system is unplugged.
The evaluation board is a standard ATX form factor. An ATX chassis may be used if a protected environment is desired. If a chassis is not used, standoffs must be used to elevate the board off the working surface to protect the memory and to protect from any accidental contact to metal objects.
3. Check the jumper default position setting. Re for jumper location. Jumper J6H1 is used to clear the CMOS memory. Make sure this jumper is set for normal operation.
4. Be sure to populate the following hardware on your evaluation board: — One Intel® CoreTM 2 Duo processor— One processor thermal solution— One DDR2 SODIMM (200-pin) Intel® CoreTM 2 Duo processor with the Mobile Intel® 945GME Express Chipset Order Number: 317443-001US Getting Started—Intel® 945GME Express Chipset

Mechanical Form Factor
The evaluation board conforms to the ATX form factor. For extra protection in a development environment, you may want to install the evaluation board in an ATX chassis. Internal and rear panel system I/O connectors are described in An overview of connector and slot locations is prov.
The objective of thermal management is to ensure that the temperature of each component is maintained within specified functional limits. The functional temperature limit is the range within which the electrical circuits can be expected to meet their specified performance requirements. Operation outside the functional limit can degrade system performance and cause reliability problems.
The development kit is shipped with a fansink thermal solution for installation on the processor. This thermal solution has been tested in an open-air environment at room temperature and is sufficient for evaluation purposes. The designer must ensure that adequate thermal management is provided for any customer-derived designs.

The Intel® 945GME Express Chipset board uses a CK-410M and CK-SSCD compatible solution. The CK-SSCD solution offers improved EMI performance by spreading the radiated clock emissions over a wider spectrum than a single frequency. This is accomplished while controlling the clock frequency deviation such that system performance is not compromised. The FSB frequency is determined from decoding the processor BSEL[2:0] pin settings.
Real Time Clock
An on-board battery at BT5H1 maintains power to the real time clock (RTC) when in a mechanical off state. A CR2032 battery is installed on the Intel® 945GME Express Chipset development kit.
The processor has a thermal diode for temperature monitoring. The SMC thermal monitoring device will throttle the processor if it becomes hot. If the temperature of the processor rises too high, the SMC will alternately blink the CAPS lock and NUM lock LEDs on the board, and the board will shut down.

Transition to S3
If enabled, the transition to S3 from the full-on state can be accomplished in the • The OS performs the transition through software.
• Press the front panel power button for less than four seconds (assuming the OS power management support has been enabled).
The power button is accessed by adding a switch to the pins 5 and 6 on the front panel header J8J1.
Transition to S4
"Wake on S4" (Suspend to disk) is controlled by the operating system.
Transition to S5
The transition to S5 is accomplished by the following means: • Press the front panel power button for less than four seconds (if enabled through • Press the front panel power button for more than four seconds to activate power button override.
Transition to Full-On
The transition to the Full-On state can be from S3 or S5. The transition from S3 is a low latency transition that is triggered by one of the following wake events: • Power management timer expiration• Real Time Clock (RTC) triggered alarm• Power button activation• USB device interrupt• ICH7M pin PME# assertion• AC power loss For AC power loss, the system operation is defined by register settings in the Intel ICH7-M. Upon the return of power, a BIOS option, set prior to the power loss, allows the system to either go immediately to the S5 state, or reboot to the Full-On state, no matter what the state was before the power loss. External logic for this functionality is not necessary. If the BIOS remains in the S5 state after AC power loss, only the power button or the RTC alarm can bring the system out of the S5 state. The status of enabled wake events will be lost.
Power Measurement Support
Power measurement resistors are provided on the platform to measure the power of most subsystems. All power measurement resistors have a tolerance of 1%. The value of these power measurement resistors are 2 mΩ by default. Power on a particular subsystem is calculated using the following formula: P = R Intel® CoreTM 2 Duo processor with the Mobile Intel® 945GME Express Chipset Order Number: 317443-001US Intel® 945GME Express Chipset—Theory of Operation
R is the value of the sense resistor (typically 0.002 Ω) V is the voltage measured across the sense resistor.
It is recommended that the user use an oscilloscope or high precision digital multi- meter tool such as the Agilent* 34401A digital multi-meter. Such a meter has 6½ digits of accuracy and can provide a much greater accuracy in power measurement than a common 3½ digit multimeter.

Heat Sink Installation Instructions—Intel® 945GME Express Chipset
Appendix A Heat Sink Installation Instructions
It is necessary for the Intel® CoreTM 2 Duo processor to have a thermal solution attached to it in order to keep it within its operating temperature.
A heat sink is included in the kit. To install the heat sink: 1. Remove the heatsink from its package and separate the fan heatsink portion from the heatsink backplate.
Figure 6.
Heatsink and Backplate
2. Examine the base of the heatsink, where contact with the processor die is made. This surface should be clean of all materials and greases. Wipe the bottom surface clean with isopropyl alcohol.
3. Place the backplate on the underside of the board so that the pins protrude through the holes in the system board around the processor.

4. Clean the die of the processor with isopropyl alcohol before the heatsink is attached to the processor. This ensures that the surface of the die is clean.
5. Remove the tube of thermal grease from the package and use it to coat the bottom of the heatsink thermal plate with the thermal grease.

7. While keeping the activation arm compressed, place the heatsink over the pins of the heatsink backplate. Lower the heatsink until the lugs have inserted into the base of the heatsink. Slide the heatsink over the lugs on the backplate pins so that the base is directly over the processor die and the pins on the backplate have traveled the entire length of the channel in the heatsink base. Slowly let go of the activation arm until the base of the heatsink makes contact with the processor die. The heatsink base should be flat on top of the processor die. Figure 10.
