Features
• Stable resistor network
• High speed termination network
• 8 or 12 terminating lines/package
• Saves board space and reduces assembly cost
Product Description
CAMD’s PRN100/110 Isolated Resistor Termination
Networks offer high integration and performance in a
miniature QSOP or SOIC package, which saves critical
board area and provides manufacturing cost and
reliability efficiencies.
Why thin film resistor networks? A terminating resistor is
used to reduce or eliminate unwanted reflections on a
transmission line or in some cases provide DC pull-up/
pull-down. It can perform this function only when its

Applications
• Series termination
• Parallel termination
• Pull up/pull down
• Digital pulse squaring
• Coding and decoding
• Telemetry
Refer to AP-201 Termination Application Note for further
information.
resistance value is closely matched to the characteristic
impedance of the transmission line. The resistors used
for terminating transmission lines must be noiseless,
stable, and functional at high frequencies. Unlike thin
film-based resistor networks, conventional thick film
resistors used for this purpose are not stable over
temperature and time, and may have functional limita-
tions when used in high frequency applications.
