What does ppm mean in oscillator?
parts per million
Oscillators and other frequency control devices specify their frequency variation in units of parts per million (ppm).
What does OCXO mean?
Oven Controlled Crystal
OCXO actually stands for Oven Controlled Crystal (Xtal) Oscillator. OCXO are the top performing type of quartz crystal oscillator at the expense of power. Other types of quartz crystal oscillators include TCXO, VCXO, and just plain XOs. You can read more about all the different types of quartz crystal oscillators here.
What is XO oscillator?
Typical Frequency Adjustment Range: ±10 ppm to ±20 ppm. The crystal controlled clock oscillator (XO) is a device that achieves its temperature stability from the quartz crystal’s inherent temperature stability. This characteristic is typically specified in tens of parts per million (ppm).
What is oscillator stability?
The “frequency stability” of an oscillator is a term used to characterize how small the frequency fluctuations of the oscillator signal are. We usually refer to frequency stability when comparing one oscillator with another.
What does Tcxo stand for?
Temperature Compensated Crystal Oscillator
Apr 10, 2018. A TCXO or a Temperature Compensated Crystal Oscillator is a crystal oscillator specially designed to operate in high-temperature environments. The oscillation frequency of a regular crystal oscillator changes/fluctuates as the temperature rises, resulting in an unstable oscillation frequency.
What is piezoelectric oscillator?
Definition of piezoelectric oscillator : a vacuum-tube circuit that contains a plate of piezoelectric material and is used as a generator of electric oscillations of a particular frequency.
What is Tcxo clock?
A TCXO (Temperature compensated crystal oscillator) is a crystal oscillator with a temperature-sensitive reactance circuit in its oscillation loop to compensate the frequency-temperature characteristics inherent to the crystal unit.
