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.
