Oscillators: XG-2102CA 125.0000M-LGPA

Oscillators are commonly used in electronic applications such as frequency meters, voltage regulators, filters and amplifiers, clocks, radios, and much more. Amongst oscillators, the XG-2102CA 125. 0000M-LGPA is used for frequency and phase-control applications, primarily within the instrumentation and control (I&C) market.

Application Field of XG-2102CA 125.0000M-LGPA

The XG-2102CA 125.0000M-LGPA is a Voltage-Controlled Oscillator (VCO) designed to generate accurate and stable frequencies over a wide range and under stringent environmental conditions, with low phase noise. It is an ideal choice for application in the field of frequency and phase control, including PLL, CODEC, and DDS, in telecom and consumer electronics markets.The XG-2102CA 125.0000M-LGPA can generate frequencies up to 125.00 GHz. It is capable of wide variation in the frequency depending on the prime voltage, which is adjustable using an external control voltage (VC) from 0-4.5V. Consequently, the XG-2102CA 125.0000M-LGPA allows for precise frequency control and stability over wide temperature ranges. It also offers high-efficiency phase noise at the low voltage range of 1.25V. This phase noise generates low N-th harmonic spurs, suppressing undesired spurious signals, from -90dBc/Hz to -120dBc/Hz at a frequency offset of 1MHz.

Working Principle of XG-2102CA 125.0000M-LGPA

The XG-2102CA 125.0000M-LGPA is based on a quarter-wave PLL architecture containing an oscillator and a PLL loop filter. The oscillator is operated as an LC tank circuit, and its output frequency is determined by an equation that is dependent on values of L and C. Thus, by changing one of these values, the output frequency can be adjusted to reach the desired frequency. This is precisely what is done when the XG-2102CA 125.0000M-LGPA is in use.The PLL loop filter is designed to stabilize the output signal and to counteract the frequency drift that is caused by environmental conditions such as temperature. This filter adjusts the output frequency based on an external control voltage, which can be adjusted in order to maintain the desired accuracy.Once the PLL loop filter is enabled, the frequency drift becomes greatly reduced. This increase in stability allows for the constant generation of stable accurate signals. The resultant output voltage amplifies the signal compared to other types of VCOs. Thus, it provides better performance in terms of characteristic frequency and spectral purity. These features make the XG-2102CA 125.0000M-LGPA an ideal choice for frequency control applications.

Conclusion

The XG-2102CA 125.0000M-LGPA is an effective choice for frequency control applications, providing accurate and stable signals over a wide range of frequencies. It features low phase noise, precise frequency control, high-efficiency phase noise at the low voltage range of 1.25V, and great stability in spite of environmental conditions. All these benefits make the XG-2102CA 125.0000M-LGPA a superior oscillator in comparison to other types of VCOs.
