Low Voltage,1:18 Clock Distribution Chip

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

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 50? 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 supplying clocks for a high performance Pentium II? microprocessor based design.

Features

  • 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
