MOTOROLA MPC909

SEMICONDUCTOR TECHNICAL DATA
" ! The MPC909 is a 1:18 low voltage clock distribution chip. The 18
outputs are LVCMOS or LVTTL compatible and feature the drive strength
to drive 50Ω series or parallel terminated transmission lines. With
output–to–output skews of 250ps, the MPC909 is ideal as a clock
distribution chip for the cost sensitive, high performance designs. With
low cost as one of the critical parameters, technology, design and test
choices were made which adversely affect part–to–part skew
performance. For very high performance applications, where part–to–part
skew is critical, please refer to the MPC940 datasheet.

With a low output impedance, in both the HIGH and LOW logic states,
the output buffers of the MPC909 are ideal for driving series terminated
transmission lines. More specifically, each of the 18 MPC909 outputs can
drive two series terminated 50Ω transmission lines. With this capability,
the MPC909 has an effective fanout of 1:36 in applications where each
line drives a single load. With this level of fanout, the MPC909 provides
enough copies of low skew clocks for many high performance
synchronous systems.
The MPC909 is fully 3.3V compatible. The 32–lead TQFP 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 0.8mm pin spacing.
