MPC9109

Freescale Semiconductor Technical Data DATA SHEET MPC9109 Rev. 2, 08/2005 Low Voltage 1:18 Clock Distribution Low Voltage 1:18 Clock Chip MPC9109 Distribution Chip MPC9109 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 Ω 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 supwww.DataSheet4U.com plying 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, 3.3 V core and 2.5 V output Single 3.3 V VCC supply voltage for 3.3 V outputs Single 2.5 V VCC supply voltage for 2.5 V I/O LOW VOLTAGE 1:18 CLOCK DISTRIBUTION CHIP FA SUFFIX 32-LEAD LQFP PACKAGE CASE 873A-04 Functional Description AC SUFFIX 32-LEAD LQFP PACKAGE Pb-FREE PACKAGE CASE 873A-04 With a low...
