Description
Pericom Semiconductor’s PI6C clock series are produced using the
company’s advanced submicron CMOS technology, achieving
industry leading speed.
PI6C102-16 is a high-speed, low-noise, clock generator that works
with Pericom’s PI6C18x clock buffer to meet all clock needs for
Mobile Intel Architecture platforms. CPU and chipset clock fre-
quencies of 66.6 MHz and 100 MHz are supported.
Split supplies of 3.3V and 2.5V are used. The 3.3V power supply
powers a portion of the I/O and the core. The 2.5V is used to power
the remaining outputs. 2.5V signaling follows JEDEC standard
8-X. Power sequencing of the 3.3V and 2.5V supplies is not
required.
An asynchronous PWRDWN# signal may be used to orderly power
down (or up) the system.
PI6C102-16 is –0.6% down spread, where as PI6C102-16B is
±0.75% center spread.
PI6C102-16D is the high drive version of PI6C102-16
