LOW VOLTAGE, 1:27 CLOCK DISTRIBUTION CHIP

MPC941

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 50 Ω series or parallel terminated transmission lines. With output-to-output

skews of 250 ps, 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.

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 50 Ω 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 3.3 V and 2.5 V compatible. The 48-lead LQFP package was chosen to optimize performance, board

space and cost of the device. The 48-lead LQFP has a 7x7 mm body size.
