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 50鈩?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鈥搇ead TQFP package was chosen to optimize performance, board space and
cost of the device. The 32鈥搇ead TQFP has a 7x7mm body size with a conservative 0.8mm pin spacing.
