PAC002SPFQ

P/Active™ 1%Tolerance Series/ParallelTermination Network

Features

Applications

• Minimal Ground Bounce, Cross-Talk

• Stable 1% Absolute Tolerance elements

• 6 terminating lines per QSOP package

• Save board space and reduces assembly cost

• Minature 16-pin QSOP package

• High speed server and workstation terminations

(DDR, SSTL, and NTL)

Product Description

The Series/Parallel Termination Network provides high

performance, superior reliability, and low cost through

manufacturing efficiency. The termination resistor

elements are fabricated using state-of-the-art thin film

manufacturing technology, well known for its ability to

achieve tight tolerances and precision matching. This

integrated solution is silicon-based and has the same

reliability characteristics as any of today’s microproces-

sor products. The thin film resistors have very excellent

stability over temperature, applied voltage, and life. In

addition, the QSOP industry standard packaging is easy

to handle in manufacturing, and enjoys the same high

yields as typical semiconductor products.

High speed logic devices such as NTL demand unique,

high speed bus terminations. The Series/Parallel

Termination Network provides 6 terminating channels

per package and optimizes signal integrity by reducing

reflections and ringing. The termination is in standard

values shown below and is ideal for use in NTL buses.

The device features a flow through design for the series

terminations. Ground-bounce and cross-talk are mini-

mized using a proprietary die design which includes

multiple die to package connections to the termination

voltage. In addition, the resistors are trimmed to a tight

absolute tolerance of 1%, which provides tight imped-

ance-matching and results in greatly reduced reflections.
