    Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a compensated microelectromechanical oscillator, having a microelectromechanical resonator that generates an output signal and frequency adjustment circuitry, coupled to the microelectromechanical resonator to receive the output signal of the microelectromechanical resonator and, in response to a set of values, to generate an output signal having second frequency. In one embodiment, the values may be determined using the frequency of the output signal of the microelectromechanical resonator, which depends on the operating temperature of the microelectromechanical resonator and/or manufacturing variations of the microelectromechanical resonator. In one embodiment, the frequency adjustment circuitry may include frequency multiplier circuitry, for example, PLLs, DLLs, digital/frequency synthesizers and/or FLLs, as well as any combinations and permutations thereof. The frequency adjustment circuitry, in addition or in lieu thereof, may include frequency divider circuitry, for example, DLLs, digital/frequency synthesizers (for example, DDS) and/or FLLs, as well as any combinations and permutations thereof.

    Abstract: A thin and highly stable piezoelectric oscillator is provided with a piezoelectric vibrator, a mother printed board which supports a piezoelectric vibrator main body on its one face and connects lead terminals to a wiring pattern, oscillating circuit parts which are mounted on one face of the mother printed board to be disposed in close contact with one face of the piezoelectric vibrator main body, adjusting circuit parts which are mounted on the other face of the mother printed board, an internal printed board which is provided in contact with the other face of the piezoelectric vibrator main body, and heater resistors which are mounted on the internal printed board to be disposed in close contact with the other face of the piezoelectric vibrator main body. Thus, since such a configuration is employed that, while the oscillating circuit parts mounted on the mother printed board are brought in close contact with the one face of a metal case of the piezoelectric vibrator, the heater resistors mounted on the flexible printed board are brought in close contact with the other face of the metal case for the piezoelectric vibrator, not only the heater resistors heat the piezoelectric vibrator but also it indirectly heats the oscillating circuit parts efficiently.

    Abstract: A dual-cavity temperature compensated crystal oscillator (100) provides a three-layer ceramic package (110), with a crystal (170) sealed in a well or cavity (148). Oscillator components (180-184) such as a compensation circuit and an oscillator are attached through screened solder onto the back side of the ceramic package (110) and are encapsulated within potting compound or encapsulant. Electrical connection is provided between the oscillator and compensation circuitry and the piezoelectric element (170) to produce a frequency-controlled oscillator. After frequency tuning, a hermetic seal is provided between a cover (160) and ledge (140) to hermetically seal the cavity (148).
