Mobile Intel Pentium 4 Processor-M Datasheet
affect the long term reliability of the processor. For further information and design guidelines, refer
to the Mobile Intel Pentium 4 Processor-M and Intel 845MP/845MZ Chipset Platform Design
Guide.
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. For more details on decoupling recommendations,
please refer to the Mobile Intel Pentium 4 Processor-M and Intel 845MP/845MZ Chipset
Platform Design Guide.
2.3.2
System Bus AGTL+ Decoupling
The Mobile Intel Pentium 4 Processor-M integrates signal termination on the die and incorporates
high frequency decoupling capacitance on the processor package. Decoupling must also be
provided by the system motherboard for proper AGTL+ bus operation. For more information, refer
to the Mobile Intel Pentium 4 Processor-M and Intel 845MP/845MZ Chipset Platform Design
Guide.
2.3.3
System Bus Clock (BCLK[1:0]) and Processor Clocking
BCLK[1:0] directly controls the system bus interface speed as well as the core frequency of the
processor. As in previous generation processors, the Mobile Intel Pentium 4 Processor-M core
frequency is a multiple of the BCLK[1:0] frequency. Refer to Table 2 for the Mobile Intel Pentium
4 Processor-M supported ratios.
