High Performance GTL Termination Network for Socket 370 Processors

Features

• 24 terminations in a single package

• 5 chip solution for all 119 GTL terminations

• High speed termination network

• Center ground pin placement reduces ground

bounce and eases board layout

• Very low cross-talk

• Saves board space and reduces assembly cost

Application Information

High speed microprocessors demand unique, high

speed bus termination. The PACGTL Termination

Network provides 24 terminations per package and

meets the requirements for high speed terminations.

The termination resistor values are 56 or 120 ohms

each. Five devices provide the necessary terminations

for the 32-bit address bus, 64-bit data bus, and the

control of status signals. Potential board layout solutions

are included in this datasheet.

This termination network provides high performance,

high reliability, and low cost through manufacturing

Applications

• High Performance Servers

• High Performance Desk Top Systems

• Intel Celeron™ and Pentium™ CPUs

STANDARD CONFIGURATION

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 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 (SSOP) industry standard packag-

ing is easy to handle in manufacturing and yields high

reliability similar to other semiconductor components.
