PI6C105 - Pericom Semiconductor

PI6C105 Precision Clock Synthesizer

The PI6C105 is a high-speed, low-noise clock generator designed to work with the PI6C18x family of clock buffers 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.
