DNA SERIES
Low parasitics, fast reverse recovery time, and a
low forward voltage characteristic make KOA’s DNA
Schottky diode network an excellent bus terminator
for very high speed I/O. This network offers the
designer a single package solution to address
overshoot and undershoot problems, ringing, and
bus reflections that are common to high speed I/O.
Today these networks are commonly used to
optimize bus performance in high end computers,
external data storage peripherals, LAN networks,
and many other applications where high transfer
rates are necessary.
