Product Description

The new PI6C49019 is a high integration clock generator intended for all kinds of embedded applications and networking application with PCIe interface. The device is the most cost effective way to generate multi-frequencies and multi-outputs clocks from a 25MHz crystal and reference clock. The device can generate four pairs low power 100MHz HCSL outputs for PCIe, one single-ended 25MHz and 125 MHz output, one single-ended
48MHz and 19.2 MHz output, and one single-ended 33.33 MHz or 67.33MHz output with spread spectrum. Using a serially programmable SMBus interface, the PI6C49019 incorporates spread spectrum modulation on the four 100 MHz PCI-Express outputs with -0.5% down spread and the 33.33MHz/ 67.33 MHz output with down spread.
