3-Pin SOT-23 package
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 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.
Applications
Clock termination
Point of contact filtering
Low pass filtering
EMI/RFI filtering
C1720101
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.
