Description
The PI6C49018 is a clock generator device intended for PCI-
Express/networking applications. The device includes four 100
MHz differential outputs for PCI-Express with low power HCSL
structure, one CMOS 125 MHz output, and one CMOS 66.66
MHz, and one CMOS 80 MHz output with spread spectrum.
Using a serially programmable SMBus interface, the PI6C49018
incorporates spread spectrum modulation on the four 100 MHz
PCI-Express outputs with -0.5% down spread and the 80 MHz
output with selectable down spread.
