PACRAMBUS-1

HIGH PERFORMANCE RAMBUS TERMINATION NETWORK

FOR RIMM CONNECTOR

Features

Applications

Rambus Memory System

2 chip solution for all Rambus load

terminations, in 20-pin QSOP narrow package

14 Terminations in a single package

1% absolute tolerance 28 ohms

terminations across temperature range

Center ground pin placement reduces

ground bounce and eases board layout

Very low cross-talk

Saves board space and reduces assembly cost

Product Description

The Direct Rambus memory interface transfers data at both edges of a 400MHz clock resulting in an 800MHz transfer rate.

The Rambus channel uses a memory controller on one end of the bus, terminations at the other end, and the RIMM

modules in between. The Rambus channel contains control signals and data bus lines that must be terminated in order to

prevent any reflections. California Micro Devices PAC RAMBUS-1 integrates fourteen 28-ohm resistors specified at 1%

absolute tolerance across the commercial temperature range.

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 todays 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 semiconductor components.
