PACRPI
P/Active™ 1% Tolerance Precision Isolated Series Termination Network
Features
• Highly integrated series termination network
• 1% absolute tolerance terminations
• Ultra-low cross talk
• 11 terminating lines/package
• Saves board space and improves system reliability
• Reduces assembly cost and rework
Applications
• PC Desktop and PC-based Server systems
• Engineering Workstations
• Embedded RISC processor systems
• Series Termination
Product Description
The PAC™RPI series terminator network offers high
performance, high reliability, and low cost through
manufacturing efficiency. The resistor termination
elements are fabricated using state-of-the-art thin film
manufacturing. The resistor elements are specified at
1% tolerance for the most demanding termination
requirements. This integrated solution
†
is silicon-based
and has the same reliability characteristics as any of
today’s microprocessor products. The thin film resistors
have excellent stability over temperature, applied
voltage, and product life. In addition, the QSOP industry
standard packaging is easy to handle in manufacturing
and provides interconnect reliability on par with other
common semiconductor components.
