Filters at source of emissions. Stable resistor-capacitor network. Ideal for high-speed logic. Low lead inductance. Reduces board space compared to discretes. 3-Pin SOT-23 package. Clock termination. Point of contact filtering. Low Pass Filter. EMI/RFI filtering. High speed microprocessor systems like Intel's Pentium, DEC's Alpha, Motorola's 68K and PowerPC , Sun's SPARC, MIPs, and other RISC-based system require well-controlled and precise closk signals to maintain a high performance synchronoussystem. However, very fast edge rated clock signals exhibit transmission line effects on the clock lines resulting in undershoot and overshoot disturbances. CAMD's SWCKT resistor-capacitor integrated thin film networks are specifically designed to eliminate 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. These networks are fabricated on a silicon substrate using advanced thin film technology. They have low parasitic inductance compared to discrete and conventional thinck film filters and provide effective AC termination and EMI/RFI noise suppression over a wide range of frequencies. The SWCKT 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. Semiconwell manufactures passive network components, integrated active and passive devices, resistor networks, capacitor networks, schottky and zener diode networks, and npn, pnp transistors arrays that perform the following functions: series and parallel linear and nonlinear GTL, AC, Diode, Thevenin termination networks, precision thin film resistor capacitor networks (RC networks), isolated, bussed resistor networks including zero ohms jumper arrays, voltage divider networks, resistor networks for audio applications, EMI, RFI and ESD zener clamped diodes and transient voltage suppressors networks, EMI/RFI filter networks and clock terminations. Semiconwell's proprietary semiconductor technology, advanced thin films processes, in house assembly and packaging technologies allow manufacturing of flip chip CSP chip scale and MLF molded lead frame surface mount integrated passive networks that include unprecedented large capacitors >1microfarad (1µF) and giga ohms resistors (GW).
