◇ 产品简介 ◇

   The MC88PL117 utilizes proven phase–locked loop clock driver technology to create a large fan–out，multiple frequency and phase,low skew clock driver.The 88PL117 provides the clock frequencies necessary to drive systems using the PowerPCE 601 microprocessor and the PentiumE microprocessor (see applications section for  detai-ls)A total of 14 high current, matched impedance outputs are available in 8 programmable output frequency and phase configurations.Output frequencies are referenced to a system frequency,Q，and are available at 2X, 1X, and 1/2X the Q frequency.Four programmable input frequency multiplication ratios can be programmed to provide outputs at 1X,2X,and 4X the system frequency Q. Details on the programmable configurations can be found in the applications section of this data sheet
