So, where does that leave the classic high-performance crystal oscillator? The simple answer might be in high-performance applications where a "service call" is simply out of the question.
Considering the upper-mentioned, this article proposes a 16.384 MHz Voltage Controlled Crystal Oscillator (VCXO) crystal oscillator used as reference for time scheduling (16.384 MHz divided by 500 equals 32.768 Hz--the most commonly used frequency in clock and time applications) and as a frequency reference to one or more Phase Locked Loop (PLL) circuits responsible to generate the required frequencies.

The PN9276 includes a microwave mixer and a low-noise, YIG-based, 100-MHz step synthesizer that generates a 4-GHz to 9-GHz signal from a 100-MHz crystal oscillator phase-locked to a 10-MHz crystal oscillator.
The model 5100 is a digital indirectly compensated crystal oscillator (DICXO) that provides a pure, ultra-clean, crystal-controlled radio frequency signal for applications where elimination of jitter, microjumps, perturbations and frequency "pops" is critical in a non-ovenized crystal oscillator.
