Description
The PI6LC48H04 is a clock generator compliant to PCI Express®
3.0/2.0/1.0, Ethernet and other requirements. The device is used
for networking or embedded systems.
The PI6LC48H04 provides four differential (Low Power HCSL)
or LVDS outputs. Using Pericom's patented Phase Locked Loop
(PLL) techniques, the device takes a 25MHz crystal input and
produces four pairs of differential outputs (HCSL) at 156.25MHz,
100MHz, 125MHz, 133.33MHz and 200MHz clock frequencies.
