PRC207/298/299
Clock Terminator and Local EMI/RFI Filter
Features
Applications
• Filters at source of emissions
• Clock termination
• Point of contact filtering
• Low pass filtering
• EMI/RFI filtering
• Stable resistor-capacitor network
• Ideal for high-speed logic
• Low lead inductance
• Reduces board space by 70% vs. 1206 discretes
and component count by more than 50%
Product Description
High speed microprocessors like Intel’s Pentium® Pro,
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 PRC207/298/299 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.
CAMDs PRC207/298/299 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 “distrib-
uted” AC terminators when filtered lines are dispersed
across the board.
