Product Description resistance value is closely matched to the characteristic impedance of the transmission line. The resistors used for terminating transmission lines must be noiseless, stable, and functional at high frequencies. Unlike thin film-based resistor networks, conventional thick film resistors used for this purpose are not stable over temperature and time, and may have functional limitations when used in high frequency applications. CAMD's PRN100/110 Isolated Resistor Termination Networks offer high integration and performance in a miniature QSOP or SOIC package, which saves critical board area and provides manufacturing cost and reliability efficiencies. Why thin film resistor networks? A terminating resistor is used to reduce or eliminate unwanted reflections on a transmission line or in some cases provide DC pullup/pull-down. It can perform this function only when its Schematic Configurations 7 8 R R1 1 6 2 5 R 3 14 R 13 R R1 4 1 2 8-pin (SOIC) 19 20 R R1 1 18 2 3 16 R 4 11 R 3 10 R 4 9 R 5 R 6 16 8 15 R1 R 1 7 15 R 5 14 R 6 13 R 7 12 R 8 11 R 9 R 13 R 3 12 R 11 R 4 10 R 5 6 9 R 7 R 8 16-pin (SOIC, QSOP) 24 R 10 14 2 14-pin (SOIC) 17 R 12 23 R1 1 22 R 2 20-pin (SOIC, QSOP) 21 R 3 20 R 4 19 R 5 18 R 6 17 R 7 16 R 8 15 R 9 14 R 10 13 R 11 R 12 24-pin (QSOP) Standard Part Ordering Information Package Tape & Reel Part Marking Narrow SOIC PRN10016NxxxxFAP PRN10016NxxxxFAP QSOP PRN11024xxxxFAP PRN11024xxxxFAP C0970500 (c) 2001 California Micro Devices Corp.
