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 compat-

ible and feature the drive strength to drive 50Ω series or parallel termi-

nated 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.

LOW VOLTAGE

1:18 CLOCK

DISTRIBUTION CHIP

• 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 V_CC

• 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 termi-

nated 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.

32–LEAD LQFP PACKAGE

CASE 873A

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 V_CCpower 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.
