The MPC942 is a 1:18 low voltage clock distribution chip with 2.5V or
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 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. LVPECL Clock Input 2.5V LVCMOS Outputs for Pentium II Microprocessor Support 200ps Maximum Targeted Output–to–Output Skew Maximum Output Frequency of 250MHz @ 3.3 VCC 32–Lead LQFP Packaging Single 3.3V or 2.5V Supply
With a low output impedance (≈12Ω), in both the HIGH and LOW logic
states, the output 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.
The differential LVPECL inputs of the MPC942P allow the device to interface directly with a LVPECL fanout buffer like the
MC100EP111 to build very wide clock fanout trees or to couple to a high frequency clock source. The OE pins will place the
outputs into a high impedance state. The OE pin has an internal pullup resistor.
The MPC942 is a single supply device. The VCC power pins require either 2.5V or 3.3V. The 32–lead LQFP package was
chosen to optimize performance, board space and cost of the device. The 32–lead LQFP has a 7x7mm body size with a
conservative 0.8mm pin spacing.
