Description
The PI6C102 is a high-speed low-noise clock generator designed to work with the Pericom’s PI6C18x clock buffer 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 PWRDWN# signal may be used to orderly power down (or up) the system.
