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

• Telemetry

resistance value is closely matched to the characteris-
tic 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
limitations when used in high frequency applications.
