PRC202/212
CALIFORNIA MICRO DEVICES
AC Termination Network
Features
• Stable resistor-capacitor network
• No signal delays
• 18 terminating lines/package
• Saves board space and component cost
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.
