MPC942C

MOTOROLA Freescale Semiconductor, Inc. SEMICONDUCTOR TECHNICAL DATA Order this document by MPC942C/D Low Voltage 1:18 Clock Distribution Chip MPC942C Freescale Semiconductor, Inc... The MPC942 is a 1:18 low voltage clock distribution chip with 2.5V or 3.3V LVCMOS output capabilities. The device is offered in two versions; the MPC942C has an LVCMOS input clock while the MPC942P has a LVPECL input clock. The 18 outputs are 2.5V or 3.3V LVCMOS compatible and feature the drive strength to drive 50Ω series or parallel terminated transmission lines. With output–to–output skews of 200ps, the MPC942 is ideal as a clock distribution chip for the most demanding of synchronous systems. The 2.5V outputs also make the device ideal for www.DataSheet4U.com supplying clocks for a high performance Pentium II™ microprocessor based design. LOW VOLTAGE 1:18 CLOCK DISTRIBUTION CHIP LVCMOS/LVTTL Clock Input 2.5V LVCMOS Outputs for Pentium II Microprocessor Support 150ps Maximum Targeted Output–to–Output Skew Maximum Output Frequency of 250MHz @ 3.3 VCC 32–Lead TQFP Packaging Single 3.3V or 2.5V Supply FA SUFFIX 32–LEAD TQFP PACKAGE CASE 873A–02 With a low output impedance (≈12Ω), in both the HIGH and LOW logic states, the output buffers of the MPC942 are ideal for driving series terminated transmission lines. With an output impedance of 12Ω the MPC942 can drive two series terminated transmission lines from each output. This capability gives the MPC942 an effective fanout of ...
