High end consumer and professional applications require crystals with a minimum number of external components. These applications typically operate under severe noise environment of large digital video processing chips. A standard crystal oscillator pad provided in commodity libraries induces high noise and jitter.Analog Bits has developed a unique low noise Crystal Oscillator macro based on a proprietary architecture that is in volume production in several high end graphics and multi-media applications. This differentiated architecture has earned outstanding reviews on high volume production boards.
