Description
The PI6C103 is a high-speed, low-noise clock generator designed
to work with the PI6C18X clock buffer to meet all clock needs
for Mobile Intel Architecture platforms. System 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 everything except the CPU clock. The 2.5V power supply is
used to power the CPUCLK 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 orderly
power down (or up) the system. CPU and PCI clocks may also be
stopped by the CPU_STOP# and PCI_STOP# signals.
The PI6C103 contains the Spread Spectrum function for only those
clocks that synchronize to the CPU clocks (CPU and PCI clocks).
