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.
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.
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
