Product Description

High speed microprocessors like Intel’s Pentium

, DEC’s

Alpha, Motorola’s 68K and PowerPC, Sun’s SPARC,

MIPs, and other RISC-based systems require well-

controlled and precise clock signals to maintain a high

performance synchronous system. However, very fast

edge rated clock signals exhibit transmission line effects

on the clock lines resulting in undershoot and overshoot

disturbances.

CAMD’s PRC298/299 SOT resistor-capacitor integrated

thin film networks are specifically designed to eliminate

transmission line effects on high speed clock and data

lines.

These networks are fabricated on a silicon substrate

using advanced thin film technology. They have low

parasitic inductance compared to discrete and conven-

tional thick film filters and provide effective AC termina-

tion.

Why thin film RC networks? The PRC298/299 is an

integrated RC network fabricated on a silicon substrate

using advanced thin film technology. This technology

insures a fixed time constant and does not create

additional skew on the clock lines. It offers very low

parasitic inductance compared to conventional discrete

thick film-based approaches and provides effective

termination at high frequencies.
