PRC207/298/299 CALIFORNIA MICRO DEVICES Clock Terminator and Local EMI/RFI Filter Features Applications * Filters at source of emissions * Clock termination * Stable resistor-capacitor network * Point of contact filtering * Ideal for high-speed logic * Low pass filtering * Low lead inductance * EMI/RFI filtering * Reduces board space by 70% vs. 1206 discretes and component count by more than 50% Product Description High speed microprocessors like Intel's Pentium(R) 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 conventional thick film filters and provide effective AC termination 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 "distributed" AC terminators when filtered lines are dispersed across the board.
