• 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.
