Electrical Specifications

2.3.1

VCC Decoupling

Regulator solutions need to provide bulk capacitance with a low Effective Series Resistance (ESR)

and keep a low interconnect resistance from the regulator to the socket. Bulk decoupling for the

large current swings when the part is powering on, or entering/exiting low power states, must be

provided by the voltage regulator solution (VR). In addition, a sufficient quality of low ESR

ceramic capacitors are required in the socket cavity to ensure proper high frequency noise

suppression. For more details on this topic, refer to the Voltage Regulator Down (VRD) 10.1

Design Guide for Desktop LGA775 Socket. Contact your Intel representative for further details and

documentation.

2.3.2

FSB GTL+ Decoupling

The Pentium 4 processor integrates signal termination on the die as well as incorporating high

frequency decoupling capacitance on the processor package. Decoupling must also be provided by

the system baseboard for proper GTL+ bus operation. Contact your Intel representative for further

details and documentation.

2.3.3 FSB Clock (BCLK[1:0]) and Processor Clocking

BCLK[1:0] directly controls the FSB interface speed as well as the core frequency of the processor.

As in previous generation processors, the Pentium 4 processor core frequency is a multiple of the

BCLK[1:0] frequency. The processor bus ratio multiplier will be set at its default ratio during

manufacturing. No user intervention is necessary; the processor will automatically run at the speed

indicated on the package.

The Pentium 4 processor uses a differential clocking implementation. For more information on the

Pentium 4 processor clocking, contact your Intel representative.
