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.
