Description
The PI6LC48S04 is a 4-output clock synthesizer designed for se-
rial reference clock applications. The device generates four cop-
ies of a selectable 250MHz, 156.25MHz, 125MHz or 100MHz
clock signal with 0.34ps phase jitter performance. The four
outputs are organized in two banks of two LVDS and two low
power HCSL ouputs.The device supports 3.3V and 2.5V voltage
supplies and is packaged in a small 32-lead TQFN package.
