Low Voltage,1:27 Clock Distribution Chip

The MPC941 is a 1:27 low voltage clock distribution chip. The device features the capability to select either a differential LVPECL or an LVCMOS compatible input. The 27 outputs are LVCMOS compatible and feature the drive strength to drive 50Ω series or parallel terminated transmission lines. With output-to-output skews of 250 ps, the MPC941 is ideal as a clock distribution chip for the most demanding of synchronous systems. For a similar product with a smaller number of outputs, please consult the MPC940 data sheet.
