LOW VOLTAGE 1:12 CLOCK DISTRIBUTION CHIP

The MPC948L is a 1:12 low voltage clock distribution chip. The device is pin and function compatible with the MPC948 with the added feature of 2.5V output capabilities. The device features the capability to select either

a differential LVPECL or a LVTTL compatible input. The 12 outputs are 2.5V LVCMOS or LVTTL compatible and feature the drive strength to drive 50Ωseries terminated transmission lines. With output–to–output skews of 350ps, the MPC948L is ideal as a clock distribution chip for the most demanding of synchronous systems.
