Product Description
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 minimized 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 impedance-matching and results in
greatly reduced reflections.
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鈥檚 micropro-
cessor 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.
