These oscillators have historically been built around a quartz crystal resonator connected to an analog sustaining circuit driving the crystal to vibrate at its resonant frequency.
By linking the laser cooling of the crystal resonator with the spin of the internal defect it should be possible to monitor the changes in spin configuration of the internal defect -- these changes are called Bohr spin quantum jumps -- via the mechanical resonator's vibrations.
The Si4901 reportedly removes the requirement for a costly external SRAM, uses DCXO technology to replace external VC-TXCO modules with a low-cost crystal resonator and allows handsets to be made with a phone BOM of less than USD16.
The crystal resonator is the primary factor in maintaining good phase noise performance at the lower supply voltage.
The method is based on quartz crystal microbalance (QCM), which allows to detect the mass variation per unit area by measuring the change in frequency of a Quartz Crystal resonator.
The extension of the family to cover these frequencies was achieved through the incorporation of a special AT-cut crystal resonator process.

36 psRMS) clock signal from a low-frequency crystal resonator or reference clock input.
The new additions include industrial temperature range (-40xC to 85xC) support and devices that detect the state of the USB controller's crystal oscillator driver circuit to simplify crystal resonator replacement.
Although improved insulation resistance provides some benefit to oscillator warm-up time, the primary improvement factors are the thermal capacity of the oven structure and the quick transfer of heat to the crystal resonator.
Designed to provide frequency control for transmitters or receivers in TPMS (Tire Pressure Monitor Systems) applications, NDK's two crystal resonator options--the NX5032SD and the NX8045GB--are hermetically sealed in ceramic SMD packages exceeding the tough shock, vibration, drop and acceleration requirements for TPMS applications.
Shock resistance is imparted by use of a special g-hardened crystal resonator and by solid construction.
