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.
