The MPC9449 is a 3.3V or 2.5V compatible, 1:15 clock fanout buffer  
targeted for high performance clock tree applications. With output fre-  
quencies up to 200 MHz and output skews less than 200 ps the device  
meets the needs of the most demanding clock applications.

Functional Description  
The MPC9449 is specifically designed to distribute LVCMOS compat-  
ible clock signals up to a frequency of 200 MHz. The device has 15 identi-  
cal outputs, organized in 4 output banks. Each output bank provides a  
retimed or frequency divided copy of the input signal with a near zero  
skew. The output buffer supports driving of 50Ω terminated transmission  
lines on the incident edge: each output is capable of driving either one  
parallel terminated or two series terminated transmission lines.

Two selectable LVCMOS compatible clock inputs are available. This feature supports redundant differential clock sources. In  
addition, the MPC9449 accepts one differential PECL clock signal. The DSELx pins choose between division of the input refer-  
ence frequency by one or two. The frequency divider can be set individually for each of the four output banks. Applying the OE  
control will force the outputs into high-impedance mode.  
All inputs have an internal pull-up or pull-down resistor preventing unused and open inputs from floating. The device supports  
a 2.5V or 3.3V power supply and an ambient temperature range of –40°C to +85°C. The MPC9449 is pin and function compatible  
but performance-enhanced to the MPC949. The device is packaged in a 52-lead LQFP package.
