XOs for small-cell applications

摘要

Advances in IC technology have led to enhancements in both ovenized (oven-controlled) crystal oscillators (OCXOs) and temperature-compensated, voltage-controlled crystal oscillators (TCVCXOs) that have blurred their historical differences. As technology has improved, the functionality of both types of oscillators has made it difficult for many designers to determine which technology is appropriate for a particular application. TCVCXO technology has been developed to a point where it is a viable option in applications where only OCXOs were an option.
