V
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 platform design guides. Intel strongly recommends that the layout and
decoupling recommendations in the platform design guides be followed.
FSB AGTL+ Decoupling
Intel Celeron M processors integrate signal termination on the die as well as incorporate 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
platform design guides.
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 Intel Celeron M processor core frequency is a multiple of
the BCLK[1:0] frequency. In regards to processor clocking, the Intel Celeron M processor uses a
differential clocking implementation.
Voltage Identification
The processor uses six voltage identification pins, VID[5:0], to support automatic selection of
power supply voltages. The VID pins for the processor are CMOS outputs driven by the processor
VID circuitry.
