Description

These integrated termination networks provide high

performance line termination for GTL, GTL+, and AGTL+

busses.

The patented star circuit design combined with a ceramic

substrate minimizes cross talk between channels that is

common in other termination networks and resistor arrays.

The BGA packaging has been proven to reduce rework and

improve reliability.
