Note:
Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

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 of PI6C104 may be used to orderly power down (or up) the system during power on.
