Memory & IDE Terminator
Technical
Data Sheet
RoHS Compliant Parts Available
Description
This source terminator network provides high performance
resistor termination for high-speed data 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.
