•
resistor termination for VME64 and VME64x back planes.
Designed with a ceramic substrate, this device minimizes
parasitic capacitance and inductance, a primary cause of
reduced system performance. In addition, the BGA package
eases touting design, saving the designer many hours of
printed circuit layout.
Compatible with both lead and lead
free processes
The BGA packaging has been proven to reduce rework and
improve reliability
