The MPC941 is a 1:27 low voltage clock distribution chip. The device

features the capability to select either a differential LVPECL or an

LVCMOS compatible input. The 27 outputs are LVCMOS compatible and

feature the drive strength to drive 50Ω series or parallel terminated

transmission lines. With output–to–output skews of 250ps, the MPC941

is ideal as a clock distribution chip for the most demanding of

synchronous systems. For a similar product with a smaller number of

outputs, please consult the MPC940 data sheet.

48–LEAD LQFP PACKAGE

CASE 932–02

With a low output impedance, in both the HIGH and LOW logic states,

the output buffers of the MPC941 are ideal for driving series terminated

transmission lines. More specifically, each of the 27 MPC941 outputs can

drive two series terminated 50Ω transmission lines. With this capability,

the MPC941 has an effective fanout of 1:54. With this level of fanout, the

MPC941 provides enough copies of low skew clocks for most high

performance synchronous systems.

The differential LVPECL inputs of the MPC941 allow the device to interface directly with an LVPECL fanout buffer like the

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 as 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.

The MPC941 is fully 3.3V and 2.5V compatible. The 48–lead LQFP package was chosen to optimize performance, board

space and cost of the device. The 48–lead LQFP has a 7x7mm body size.
