PACR4G

P/Active^®High Performance Bus Termination Network

Features

Applications

• Designed especially for High Performance

computers/servers

• High Performance servers

• High Performance desk top systems

• GTL, NTL, ECL terminator

• Provides high speed bus termination

• Reduces ground bounce with ground

pin placement / Ultra low crosstalk

• Terminates 20 lines in a QSOP package

Product Description

High speed microprocessors demand unique, high

speed bus termination. The PAC™R4G Termination

Network provides 20 terminations per package and

meets the requirements for high speed terminations.

ing. This integrated solution is silicon-based and has

the same reliability characteristics as any of today’s

microprocessor 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 semicon-

ductor components.

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 manufactur-
