As electronics technology continues to advance at a fast pace, the limitations of crystals and crystal oscillators as a practical approach to timing are being exposed. Higher frequencies and smaller form factors are forcing designers to use expensive, power hungry, smaller SMD crystal-based clocks that also often need additional circuitry to enable them to meet the performance requirements of the system. Furthermore, the proliferation of portable electronics equipment that is typically exposed to harsh operating conditions that include shock and vibration, has exposed the susceptibility of crystal oscillators to physical damage.

While crystal oscillators have served the electronics industry well for decades, aside from a limited number of high-end applications, the reasons for designers to consider switching to ‘crystal-free’ CMOS based timing solutions are compelling.
