The MPC9109 is a 1:18 low voltage clock distribution chip with 2.5V or 3.3V LVCMOS output capabilities. The device features the capability to select either a differential LVPECL or an LVCMOS compatible input. The 18 outputs are 2.5V or 3.3V LVCMOS compatible and feature the drive strength to drive 50Ωseries or parallel terminated transmission lines. With output–to–output skews of 200ps, the MPC9109 is ideal as a clock distribution chip for the most demanding of synchronous systems. The 2.5V outputs also make the device ideal for supplying clocks for a high

performance Pentium IImicroprocessor based design. For a higher performance version of the 9109 refer to the MPC940L data sheet.
