OCZ anounced their newest innovation for the high
speed memory market, Ultra Low Noise 2 technology. OCZ Ultra Low Noise
technology has been the staple of high quality, high performance PCB technology
for over a year. ULN 2 specifications allow OCZ modules to run more efficiently
and overclock better than any other memory on the market. Based upon the success
of ULN PCBs, OCZ Technology has improved upon the quality and design of the PCB
and is now ready to begin using PCBs based on ULN II Technology to further
reduce noise and interference on the PCB. ULN II is based on a custom-built PCB
with special emphasis on reducing this noise and interference that is present in
all electronic circuits. ULN II includes additional shielding features as well
as improved signal routing to help increase the maximum speed that can be
attained on the module.

attained on the module.

The additional shielding present helps to reduce the
interference from other nearby devices as well as on the PCB itself. Shielding
is generally accomplished through the use of large metal planes that provide
protection from electric fields. This helps to reduce the inductive interference
as well as the capacitive coupling. Improved signal routing helps to speed up
the overall module as the wire traces on the PCB are more efficiently routed so
as to minimize the capacitive and resistive nature of these interconnects as
well as find the minimum distance for critical signals. Moreover, special care
is taken in the placement and routing of rapidly switching lines to minimize the
effect of noise and interference on nearby lines. These improved features not
only allow more stable operation, but also allow the module to run at a higher
frequency than the modules based on ULN PCBs since there is less noise and
interference at the same switching speed.
