Description
The new PI6C49006 is a high performance clock generator
intended for all kinds of embedded applications, which include
Wireless AP & Femtocell BTS, Multi Function Printer, and other
PCIe/Networking applications. It is the most cost effective way
to generate a high quality, high frequency clock output from a
crystal and reference clock. The device can generate 100/125MHz
HCSL outputs for PCIe, selectable 33/50/66/100/133 LVMOS
clock for network processor and DSP and 25MHz Ethernet clock
combination.
