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.

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 and EMI/RFI noise suppression over a wide range of

frequencies.

Why thin film RC networks? The PRC207 is an inte-

grated 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.

CAMD’s PRC207 SOT resistor-capacitor integrated thin

film networks are specifically designed to eliminate

transmission line effects on high speed clock and data

lines. They are effective in suppressing EMI/RFI noise at

I/O ports and can also be used as “distributed” AC

terminators when filtered lines are dispersed across the

board.
