Product 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.
