GTL, GTL+, AGTL+ Terminator
Technical
Data Sheet
RoHS Compliant Parts Available
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.
