Description
The PI6C105 is a high-speed, low-noise clock generator designed
to work with the PI6C18x family of clock buffers to meet all clock
needs for Mobile Intel Architecture platforms. CPU and chipset
clock frequencies 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 PWR_DWN# signal may be used to power down
(or up) the system in an orderly manner.
