EG-2121CA 312.5000M-LGPAB application field and working principleOscillators are widely used in various fields of engineering, such as electronics, IT, medical technology and automotive industry, for the purpose of creating a repetitive signal. The EG-2121CA 312.5000M-LGPAB is a voltage-controlled crystal oscillator (VCXO) which is suitable for frequency adjusting applications that need to modify the frequency over a narrow range.The VCXO works by using a quartz crystal as its frequency control element. A quartz crystal can both vibrate and generate a current when supplied with an alternating voltage. The frequency of the quartz oscillations depends on the shape of the cut, the mass and the temperature. To ensure that the frequency remains stable despite environmental changes like temperature variation and load impedance, the oscillator is enclosed in a temperature compensated unit.The EG-2121CA 312.5000M-LGPAB has a frequency range of 312.5000 KHz to 312.5000 KHz with a maximum frequency stability of 10 ppm. The frequency can be adjusted using an external control voltage and the VCXO has a wide pull range of ±50 ppm to ±500 ppm. It is a wide-band device with a wide bandwidth and low phase noise.The VCXO has various applications in different industries. It is used as a frequency generation source in consumer electronics, communications, instrumentation and automotive industries. It is also used in modulation and demodulation of a wide range of communication signals. These include global positioning system (GPS) signaling and satellite communication. Telecommunication technologies such as digitalcell, GSM and WiFi also use VCXOs for frequency support.Another application for which this VCXO is suitable is in radio broadcast transmission. This is because the device can efficiently produce narrow-band signal with the needed purity of reference frequency. The EG-2121CA 312.5000M-LGPAB is also utilized in clock generators, frequency synthesizers, phase locked loops (PLLs) and calibrated clocks.Overall, the EG-2121CA 312.5000M-LGPAB is a reliable and highly efficient VCXO for frequency adjusting applications. It has a wide pull range, a wide frequency range, low phase noise and a maximum frequency stability of 10 ppm. It is suitable for applications in the consumer electronics, communications, instrumentation and automotive industries and radio broadcast transmission.
