954204 - Block Diagram
説明
954204 is a CK410M Compliant clock synthesizer. 954204 provides a single-chip solution for mobile systems built with Intel P4-M processors and Intel mobile chipsets. 954204 is driven with a 14.318MHz crystal and generates CPU outputs up to 400MHz. It provides the tight ppm accuracy required by Serial ATA and PCI-Express.
