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 50Ω series or parallel
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 microprocessor based design.

buffers of the MPC942 are ideal for driving series terminated transmission lines. With an
output impedance of 12Ω the 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.
interface. The OE pins will place the outputs into a high impedance state. The OE pin has
an internal pullup resistor.
The 32-lead TQFP package was chosen to optimize performance, board space and cost
of the device. The 32-lead TQFP has a 7x7mm body size with a conservative 0.8mm pin
spacing.
