PACR6G is same as SEMICONWELL - SWR6G/Rxxx HIGH PERFORMANCE BUSS TERMINATION NETWORK pin compatible with PACR6G THIN FILM RESISTOR NETWORKS. SWR6G/Rxxx High performance buss termination network SWR6G/Rxxx is pin compatible with PACR6G Specially applicable for Pentium or P6-class computer/servers 14 terminating lines/package Center ground pin placement reduces ground bounce High speed termination network. Saves board space and reduces assembly cost. Parallel terminations Pull up / Pull down resistors GTL/ECL logic The SWRG series are used by systems based on high-speed microprocessors like Intel i486® , Intel Pentium/P6® , Apple PowerPC and other RISC. These products are integrated thin film resistor-networks that are designed to suppress transmission line effects on high-speed data lines. The RG series solution improves performance and reduces assembly cost on passive components. These products are manufactured using advanced thin film technologies including ultra-stable and self passivating Tantalum Nitride resistors and gold interconnect metalization to achieve excellent uniformity, performance and reliability. In die form, these products are ideal for hybrid and multichip module applications. In packaged form, these products are the best solution where space and weight are a concern.

High speed microprocessors like Intel’s Pentium ® Pro Processor, demand unique, high speed bus termination schemes. The SWR6G series network provides 18 terminations per package. Four termination resistor values are available. The 47, 50 and 56 ohm terminations are suitable for use with the Intel server chip set and the 68 ohm termination is suitable for use with the Intel desktop chip set. The tight resistor tolerance minimizes noise contribution from termination mismatching. The SWR6G network offers high performance, high reliability, and low cost through manufacturing efficiency. It meets or exceeds all Intel specifications for termination performance and provides an additional degree of system noise margin. The termination resistor elements are fabricated using state-of-the-art thin film manufacturing. This highly integrated solution is silicon-based and has the same reliability characteristics as any of today’s microprocessor products. The thin film resistors have excellent stability over temperature, over applied voltage, and over product life. In addition, the QSOP industry standard packaging is easy to handle in manufacturing and provides interconnect reliability — on par with other common semiconductor components — and far better than traditional thick film-based chip products.
