NOTICE - The following device(s) are recommended alternatives:

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

Features

  • LVPECL or LVCMOS clock input
  • 2.5 V LVCMOS outputs for Pentium II microprocessor support
  • 200 ps maximum output-to-output skew @ 3.3 V output
  • Maximum output frequency of 250 MHz @ 3.3 V core
  • 32-lead QFP packaging
  • Dual or single supply device:
    Dual Vcc supply voltage, 3.3V core and 2.5V output
    Single 3.3V Vcc supply voltage for 3.3V outputs
    Single 2.5V Vcc supply voltage for 2.5V I/O
  • For replacement device use 83940DYLF
