Description
The PI6C104 is a high-speed low-noise clock generator designed
to work with the PI6C18X family of clock buffer to meet all clock
needs for Desktop Intel Architecture platforms. CPU and chipset
clock frequencies from 66.6 MHz to 112 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 (CPU and APIC). 2.5V signaling follows
JEDEC standard 8-X. Power sequencing of the 3.3V and 2.5V
supplies is not required.
An asynchronous PD# signal may be used to orderly power down
(or up) the system during power on.
