Description
The PI6LC48H02 is a clock generator compliant to PCI Express®
3.0/2.0/1.0 and Ethernet requirements. The device is used for PC
or embedded systems.
The PI6LC48H02 provides two differential (HCSL) or LVDS out-
puts. Using Pericom's patented Phase Locked Loop (PLL) tech-
niques, the device takes a 25MHz crystal input and produces
two pairs of differential outputs (HCSL) at 25MHz, 100MHz,
125MHz, 200MHz clock frequencies.
