PRC202/212 CALIFORNIA MICRO DEVICES AC Termination Network Features Applications * * * * * AC Terminator * Low Pass Filter * Power Supply Filtering Stable resistor-capacitor network No signal delays 18 terminating lines/package Saves board space and component cost Product Description matches the characteristic impedance of the transmission line. CAMD's PRC202/212 Integrated Resistor-Capacitor Termination Network is designed to eliminate transmission line effects on high speed data lines. This thin film network can support (terminate) 18 data lines, and requires no DC power. The small surface mount packages improve board yields and reliability, minimize space and routing problems on the board, and reduce assembly costs. The PRC202/212 is a space efficient and cost effective replacement for conventional MLCC surface mount chip resistors and capacitors. Passive components affect the electrical performance of electronic systems. In reality, every resistor has some parasitic series inductance and a parasitic capacitance; and every capacitor has both series resistance and inductance. At low speeds, these parasitics do not affect the performance of resistors and capacitors. However, at higher speeds, these parasitics cause mismatch in a termination. To prevent these problems in high speed digital designs, a designer must take special care in selecting passive components or networks. Why thin film RC networks? A terminating RC is used to reduce or eliminate reflections on a transmission line. It can perform this function only when its impedance value SCHEMATIC CONFIGURATION 20 19 18 17 16 15 14 13 12 11 1 2 3 4 5 6 7 8 9 10 STANDARD PART ORDERING INFORMATION Package Ordering Part Number RC Code Pins Style Tubes Tape & Reel Part Marking 101/101A 20 SOICW PRC202101K/101M/T PRC202101K/101M/R PRC202101K/101M 330/470A 20 SOICW PRC202330K/470M/T PRC202330K/470M/R PRC202330K/470M 470/330A 20 SOICW PRC202470K/330M/T PRC202470K/330M/R PRC202470K/330M 470/470A 20 SOICW PRC202470K/470M/T PRC202470K/470M/R PRC202470K/470M 500/181A 20 SOICW PRC202500K/181M/T PRC202500K/181M/R PRC202500K/181M 750/500A 20 SOICW PRC202750K/500M/T PRC202750K/500M/R PRC202750K/500M 101/101A 20 QSOP PRC212101K/101M/T PRC212101K/101M/R PRC212101K/101M 330/470A 20 QSOP PRC212330K/470M/T PRC212330K/470M/R PRC212330K/470M 470/470A 20 QSOP PRC212470K/470M/T PRC212470K/470M/R PRC212470K/470M 470/330A 20 QSOP PRC212470K/330M/T PRC212470K/330M/R PRC212470K/330M 500/181A 20 QSOP PRC212500K/181M/T PRC212500K/181M/R PRC212500K/181M 750/500A 20 QSOP PRC212750K/500M/T PRC212750K/501M/R PRC212750K/501M C1180600 (c) 2001 California Micro Devices Corp.
