SEMICONDUCTOR TECHNICAL DATA

The MPC9448 is a 3.3V or 2.5V compatible, 1:12 clock fanout buffer

targeted for high performance clock tree applications. With output

frequencies up to 350 MHz and output skews less than 150 ps, the device

meets the needs of most demanding clock applications.

• Selectable LVCMOS and differential LVPECL compatible clock inputs

• Maximum clock frequency of 350 MHz

• Maximum clock skew of 150 ps

• Synchronous output stop in logic low state eliminates output runt pulses

• High–impedance output control

• 3.3V or 2.5V power supply

• Drives up to 24 series terminated clock lines

• Ambient temperature range –40°C to +85°C

• 32–Lead LQFP packaging

FA SUFFIX

32–LEAD LQFP PACKAGE

CASE 873A

• Supports clock distribution in networking, telecommunication and

computing applications

• Pin and function compatible to MPC948

Functional Description

The MPC9448 is specifically designed to distribute LVCMOS

compatible clock signals up to a frequency of 350 MHz. Each output

provides a precise copy of the input signal with a near zero skew. The

outputs buffers support 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, independent clock inputs are available, providing support of LVCMOS and differential LVPECL clock

distribution systems. The MPC9448 CLK_STOP control is synchronous to the falling edge of the input clock. It allows the start

and stop of the output clock signal only in a logic low state, thus eliminating potential output runt pulses. 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 MPC9448 is pin and function compatible

but performance–enhanced to the MPC948.
