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
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
based design.
states, the output buffers of the MPC942 are ideal for driving series
terminated transmission lines. With an output impedance of 12
MPC942 can drive two series terminated transmission lines from each
output. This capability gives the MPC942 an effective fanout of 1:36. The
MPC942 provides enough copies of low skew clocks for most high
performance synchronous systems.

outputs into a high impedance state. The OE pin has an internal pullup resistor.
