摘要： A circuit for producing a reliable duty cycle for a low power oscillator. The circuit produces a square wave signal based on the differences between the oscillating output signal driven by a piezoelectric crystal and a phase shifted output signal. This circuit provides a quick start for a clock signal, generates a reliable fifty percent duty cycle and is better protected from common mode noise. This circuit can also be configured to be programmable to provide for an adjustable duty cycle.

摘要： A crystal oscillator circuit has capacitors that govern the resonant circuit and are designed such that they can be connected and disconnected, for frequency adjustment. A respective compensation capacitor is connected opposite and in mirror-image form to these capacitors that govern the resonant circuit. This compensation capacitor influences only the dynamic operating point, but has virtually no effect on the oscillation frequency. In consequence, it is not possible to shift the operating point during adjustment of the oscillation frequency, thus ensuring stability of the oscillating system and operation at the desired operating point.

摘要： This temperature-compensated crystal oscillator includes: a temperature sensor 11; an analog type temperature compensating section 12; a digital type temperature compensating section 13; an adder circuit 14; and a voltage controlled crystal oscillating circuit 3. The analog type temperature compensating section 12 and the digital type temperature compensating section 13 each generate temperature compensation voltages based on an input voltage corresponding to the temperature detected by the temperature sensor 11. Both of these temperature compensation voltages are added to each other by the adder circuit 14 and the resultant added voltage is applied to a voltage control terminal of the voltage-controlled crystal oscillating circuit 3. Thereby, an oscillation frequency of the voltage-controlled crystal oscillating circuit 3 is stabilized, resulting in realization of the temperature compensation of a crystal resonator 4.

摘要： A system and method for programming a digitally tunable oscillator is provided. A desired output frequency is received. A tuning effect of a set of digital tuning words on a crystal resonant frequency is determined, and valid parameters of an algorithm for translating and tuning the crystal resonant frequency to a value within an error tolerance of the desired frequency, based on the determined tuning effect are calculated. Valid parameters are preferably calculated based on an intermediate tuning value, sorted by ascending divide parameter of the algorithm, and then evaluated in sorted order for ability of a tuning effect to null frequency error to within the error tolerance. The valid set of calculated parameters are then programmed into a nonvolatile memory. The oscillator control parameters may remain unprogrammed until all necessary parameters are defined. Because the device may be programmed in a single step, without intermediate presumption of nominal crystal frequency, the final plate process may be unnecessary. A high accuracy may be obtained by searching through the complete set of available parameters for a set that meets a frequency and tolerance specification. The oscillator is preferably a Cypress CY2037 device alone or in combination with a Micro Analog Systems MAS1175 device.
