MPC9448

MOTOROLA Freescale SEMICONDUCTOR TECHNICAL DATA Semiconductor, Inc. Order Number: MPC9448/D Rev 3, 04/2003 3.3V/2.5V LVCMOS 1:12 Clock Fanout Buffer 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. MPC9448 Freescale Semiconductor, Inc... 12 LVCMOS compatible clock outputs 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 LOW VOLTAGE 3.3V/2.5V LVCMOS 1:12 CLOCK FANOUT BUFFER Supports clock distribution in networking, telecommunication and computing applications Pin and function compatible to MPC948 FA SUFFIX 32--LEAD LQFP PACKAGE CASE 873A 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 serie...
