PACR4G

High Performance Bus Termination Network

Features

• Designed especially for High Performance

computers/servers

• Provides high speed bus termination

• Reduces ground bounce with ground

pin placement / Ultra low crosstalk

• Terminates 20 lines in a QSOP package

Applications

• High Performance servers

• High Performance desk top systems

• GTL, NTL, ECL terminator

Product Description

High speed microprocessors demand unique, high

speed bus termination. The PACR4G Termination

Network provides 20 terminations per package and

meets the requirements for high speed terminations.

This Termination Network provides high performance,

high reliability, and low cost through manufacturing

efficiency. The termination resistor elements are

fabricated using state-of-the-art thin film manufacturing.

This integrated solution is silicon-based and has the

same reliability characteristics as any of today’s micro-

processor products. The thin film resistors have very

high stability over temperature, over applied voltage and

over life. In addition the QSOP industry standard

packaging is easy to handle in manufacturing and yields

a high reliability similar to other semiconductor compo-

nents.
