What does PXS mean in ELECTRONICS

PXS stands for “Phase Locked Crystal Source” and refers to a type of electronic device used to accurately generate, measure, and control the frequency of analog or digital signals. This device produces an extremely stable output signal, whose frequency is closely correlated with an input reference signal.

A PXS consists of a quartz crystal oscillator connected to a comparator circuit that monitors the difference in frequency between the input reference signal and its own output. It compares these signals at regular intervals and automatically adjusts its own frequency by adjusting the capacitance applied across the quartz crystal so that it matches as closely as possible with the input reference signal.

A Phase Lock Loop (PLL) is an electronic circuitry typically used to synchronize two signals by detecting their phase differences and correcting them using feedback. It can be used in combination with a PXS to maintain precise control over output frequency by synchronizing it to an external source.

The major benefit of using a PXS is its accuracy in controlling and maintaining the frequency of signals over time regardless of any changes in temperature, power supply fluctuations, electrostatic fields or other external factors. This makes them particularly suitable for use in critical applications such as radio transmitters or atomic clocks which require precision timing.

Due to their high level of reliability and stability, they are widely used in various industries such as telecommunications, military applications, aerospace engineering, automotive electronics and medical equipment manufacturing. Scientists also use them due to their accurate timing capabilities when conducting precise experiments.

While both devices can be used for generating frequencies with a high degree of accuracy, there are some key differences between them. Quartz oscillators rely on their mechanical properties whereas a Phase Locked Crystal Source uses electrical components along with programmable logic circuits which enable it to respond more quickly to changes in input frequencies than quartz crystals and therefore produce more stable results over time.

Digital clocks are generated by taking advantage of the ability of a Phase Locked Crystal Source to track changes in input frequencies accurately and rapidly adjust its own output accordingly. By feeding this precise timing signal into digital circuitry connected to different displays (LEDs or LCDs), it is possible generate synchronized numerical sequences which indicate hour/minute/second readings.

In addition to digital clocks, most Phase Locked Crystal Sources have adjustable outputs capable of producing either analogue or digital signals within certain specified voltage range at specific frequencies such as 50Hz/60Hz/100Hz etc. depending on user requirements.

Generally speaking most modern commercially designed models come ready-wired with connections for interfacing power supply inputs alongside I2C / SPI / UART serial communication ports for programming purposes via dedicated software utility programs supplied by manufacturers.
