... PC or embedded systems to substantially reduce Electromagnetic Interference (EMI). The PI6C557-03 provides two differential (HCSL) spread spectrum outputs. The PI6C557-03 is confi gured to select spread and clock selection. Using Pericom's patented Phase-Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces two pairs of differential outputs (HCSL) at 25MHz, 100MHz, 125MHz and 200MHz clock frequencies ...
