全球唯一可將IC內部頻率，以CMOS Output完整輸出之技術。
技術授權方式導入 Output 輸出技術，不須更改IC內部設計下即可升級。
消除IC輸出雜訊，可直接輸出完整訊號。
CMOS technology has been widely used for more than 50 years. It
delivers low cost with high yield; however due to the unbalanced CMOS
structure, it will generate high noise into power and ground. In the past 50
years of IC history our GHz CMOS output driver is the only technology
that will reduce your chip internal ground and power noise without
sacrificing your output performance. Our low noise technology allows the
output frequency to be 7 to 10 times faster than anyone else in the world.
In addition, this low noise technology allows any ICs with our output
drivers to deliver accuracy without errors. The example below shows the
output signal from our standard logic 74G32. The VCC is 3V. The output
frequency from the measurement is 2 GHz with probe load. The
maximum frequency will be more than 2 GHz. VPP is 2.075V, Vhigh is
2.175V and Vlow is 100 mV.
