General Description
The 8413S08 is a high performance PLL-based clock generator
optimized for processor core, PCI/PCI-X/PCIe bus, SGMII and
Gigabit Ethernet PHY clocks. The clock generator offers ultra-low
jitter outputs that make it ideal to serve as a central clocking device
for multiple clock destinations. The output frequencies are generated
from a 25MHz parallel resonant crystal, or external differential input
source. The industrial temperature range of the 8413S08 supports
tele-communication, networking and storage requirements.
Features
