8 / CLOCK AND OSCILLATOR SELECTOR
Embedded Intel x86 Clocks
Silicon Labs offers an family of Intel-compliant x86 clocks for embedded computing, communications and industrial
applications. These system main clock generators support a wide variety of chipsets and processors. They provide all the
necessary clock generation for the CPU, memory controller (chipset north bridge), I/O controller (chipset south bridge)
as well as the latest timing requirements for industry standards such as SATA, USB, LAN, PCI Express and legacy PCI.
