MPC9449 General Description

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 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 50W 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 reference 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.
