Data Sheet
RoHS Compliant Parts Available
Description
This system bus bias network is designed to provide high
performance resistor bias termination for single ended
parallel busses.
Designed with a ceramic substrate, this device minimizes
channel capacitance, a primary cause of reduced system
performance. In addition, the BGA package eases routing
design, saving the designer many hours of printed circuit
layout.
The BGA packaging has been proven to reduce rework and
improve reliability.
