The PL611-31-xxx is a low-cost, general purpose frequency synthesizer and a member of Micrel’s factoryprogrammable Quick Turn Clock (QTC) family. The PL611-31-xxx product family can generate any output frequency up to 200MHz from a fundamental crystal input of 10MHz to 30MHz. In addition, the complementary LVCMOS outputs can be used to drive differential LVPECL, LVDS, HCSL or CML inputs at 2.5V or 3.3V.
