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

• Eight selectable 100MHz or 125MHz clocks for PCI Express and

sRIO, HCSL interface levels
