Low Voltage, 1:27 Clock Distribution Chip

2013 Integrated Device Technology, Inc.
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
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.

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 50
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.
