Description
The MPC9449 is a 3.3 V or 2.5 V compatible, 1:15 clock fanout buffer targeted for high performance clock tree applications. With output frequencies up to 200 MHz and output skews less than 200 ps the device meets the needs of the most demanding clock applications.
Block Diagram
The MPC9449 is specifically designed to distribute LVCMOS compatible clock signals up to a frequency of 200 MHz. The device has 15 identical outputs, organized in four 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.
