PI6LC48S04数据手册集成电路（IC）的时钟发生器PLL频率合成器规格书PDF

描述 Description

The PI6LC48S04 is a 4-output clock synthesizer designed for serial reference clock applications. The device generates four copies of a selectable 250MHz, 156.25MHz, 125MHz or 100MHzclock 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 voltagesupplies and is packaged in a small 32-lead TQFN package.
