Hot-selling and scarce MPC946FA LOW VOLTAGE 1:10 CMOS CLOCK DRIVER IC QFP spot stock

Product Descriptions

The MPC946 is a low voltage CMOS, 10 output clock buffer. The 10 outputs can be configured into a standard fanout buffer or into 1X and1/2X combinations.The ten outputs were designed and optimized to drive50Ωseries or parallel terminated transmission lines.With output to output skews  of  350ps  the  MPC946  is  an  ideal  clock  distribution  chip  for synchronous systems which  need a tight  level of skew from a large number of outputs. For a similar product with more outputs consult the MPC949 data sheet.

With an output impedance of approximately 7Ω, in both the HIGH and the LOW logic states, the output buffers of the MPC946 are ideal for driving series terminated transmission lines. More specifically each of the10 MPC946 outputs can drive two series terminated transmission lines. With  this  capability,  the  MPC946  has  an  effective fanout  of  1:20  in applications using point–to–point distribution schemes.
