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.

Supply Voltage

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.
