Product Description
CAMD’s PRC202/212 Integrated Resistor-Capacitor
Termination Network is designed to eliminate transmis-
sion line effects on high speed data lines. This thin film
network can support (terminate) 18 data lines, and
requires no DC power. The small surface mount pack-
ages improve board yields and reliability, minimize
space and routing problems on the board, and reduce
assembly costs. The PRC202/212 is a space efficient
and cost effective replacement for conventional MLCC
surface mount chip resistors and capacitors.
Why thin film RC networks? A terminating RC is used to
reduce or eliminate reflections on a transmission line. It
can perform this function only when its impedance value
matches the characteristic impedance of the transmis-
sion line.
Passive components affect the electrical performance of
electronic systems. In reality, every resistor has some
parasitic series inductance and a parasitic capacitance;
and every capacitor has both series resistance and
inductance. At low speeds, these parasitics do not affect
the performance of resistors and capacitors. However, at
higher speeds, these parasitics cause mismatch in a
termination. To prevent these problems in high speed
digital designs, a designer must take special care in
selecting passive components or networks.
