Clock Terminator
Stable resistor-capacitor network Ideal high-speed logic lead inductance Reduces board space compared discretes Packages
Application
Clock termination
Product Description
High speed microprocessors like Intel's Pentium®, DEC's Alpha, Motorola's PowerPC, Sun's SPARC, MIPs, other RISC-based systems require wellcontrolled precise clock signals maintain high performance synchronous system. However, very fast edge rated clock signals exhibit transmission line effects clock lines resulting undershoot overshoot disturbances. CAMD's PRC298/299 resistor-capacitor integrated thin film networks specifically designed eliminate transmission line effects high speed clock data lines. These networks fabricated silicon substrate using advanced thin film technology. They have parasitic inductance compared discrete conventional thick film filters provide effective termination. thin film networks? PRC298/299 integrated network fabricated silicon substrate using advanced thin film technology. This technology insures fixed time constant does create additional skew clock lines. offers very parasitic inductance compared conventional discrete thick film-based approaches provides effective termination high frequencies.
