LOW VOLTAGE 1:12 CLOCK DISTRIBUTION CHIP

The MPC948 is a 1:12 low voltage clock distribution chip. The device features the capability to select either a differential LVPECL or a LVTTL compatible input. The 12 outputs are LVCMOS or LVTTL compatible and feature the drive strength to drive 50Ωseries terminated transmission lines. With output–to–output skews of 350ps, the MPC948 is ideal as a clock distribution chip for the most demanding of synchronous systems. For a similar product targeted at a lower price/performance point, please consult the MPC947 data sheet.
