Technical Data

Low Voltage 1:18 Clock

Distribution Chip

3.3 V LVCMOS output capabilities. The device features the capability to select

either a differential LVPECL or an LVCMOS compatible input. The 18 outputs are

2.5 V or 3.3 V LVCMOS compatible and feature the drive strength to drive 50 Ω

series or parallel terminated transmission lines. With output-to-output skews of

200 ps, the MPC9109 is ideal as a clock distribution chip for the most demanding

of synchronous systems. The 2.5 V outputs also make the device ideal for sup-

plying clocks for a high performance Pentium II™ microprocessor based design.

For a higher performance version of the 9109 refer to the MPC940L data sheet.

Functional Description

the output buffers of the MPC9109 are ideal for driving series terminated trans-

mission lines. With a 20 Ω output impedance the 9109 has the capability of driving two series terminated lines from each output.

This gives the device an effective fanout of 1:36. If a lower output impedance is desired please see the MPC942 data sheet. If

better performance is desired please see the MPC940L data sheet.

MC100EP111 to build very wide clock fanout trees or to couple to a high frequency clock source. The LVCMOS input provides a

more standard interface for applications requiring only a single clock distribution chip at relatively low frequencies. In addition,

the two clock sources can be used to provide for a test clock interface as well as the primary system clock. A logic HIGH on the

LVCMOS_CLK_Sel pin will select the LVCMOS level clock input. All inputs of the MPC9109 have internal pullup/pulldown resistor

so they can be left open if unused.

operate with a 3.3 V core and 3.3 V output, a 3.3 V core and 2.5 V outputs as well as a 2.5 V core and 2.5 V outputs. The 32-

lead QFP 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 0.8 mm pin spacing.

With a low output impedance (≈20 Ω), in both the HIGH and LOW logic states,

The differential LVPECL inputs of the MPC9109 allow the device to interface directly with a LVPECL fanout buffer like the
