Memory & IDE Terminator Technical Data Sheet RoHS Compliant Parts Available Features 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. 16 or 32 Bit Terminators Ultra Low I/O Coupling Slim BGA Package ±1% Resistor Tolerance Top Side Probe-able Version Available for Development RoHS Compliant Designs Available • Compatible with both lead and lead free processes • • The BGA packaging has been proven to reduce rework and improve reliability.
