1 limitation of OCXOs is their rather extended heat-up time. The oven-controlled oscillator requires time for you to stabilize its temperature and arrive at its ideal operating problems. Startup time is a vital consideration in battery-run apps the place the unit is often switched on and off. Shorter oscillator startup situations lower wasted Po

. Crystal manufacturers for that reason specify a load capacitance to set the crystal’s supposed operating frequency. A unique load capacitance will develop the wrong frequency. Every crystal's temperature security varies a bit, and the precise thermistor coefficients and values to create a great network region not constantly available. The
