Description
This SSTL_2 terminator network provides high performance
resistor termination for SSTL_2 Class I or Class II systems.
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.
