EG-2121CA 53.1250M-LHPAB Oscillators

Oscillators are widely used in electronics and are essential components of any electronic circuit. An oscillator is an electronic circuit or device which produces a periodic electronic signal on its output. The signal has a constant amplitude and a constant frequency. Oscillators are used in many applications including timers, signals for transmission of sound, logic gates, and even in computers.

Application Field

The EG-2121CA 53.1250M-LHPAB oscillator is a low-phase-noise oscillator suitable for commercial and industrial applications such as test instruments, data acquisition systems, and communications systems. Its small size makes it an ideal choice for use in space-constrained applications such as handheld instruments and automotive systems. This oscillator can generate a stable output signal with a frequency of 53.1250MHz, over an extended temperature range of –40°C to +85°C.

Working Principle

The oscillator uses a voltage-controlled oscillator (VCO) along with a PLL circuit. The VCO generates a sinusoidal waveform, whose frequency is set by DC voltage. The voltage is generated by the PLL circuit to keep the output signals’ frequency precisely regulated at 53.1250MHz. The PLL circuit also provides control over the phase of the sinusoidal wave, allowing fine tuning of the oscillator\'s output frequency accuracy. Finally, the PLL circuit also generates a stable reference voltage to drive a high stability voltage-controlled capacitor (VCO1) in the oscillatorThe EG-2121CA 53.1250M-LHPAB oscillator has a high-Q inductor-capacitor (LC) filter, to reduce the phase noise of the output signal. The filter’s high-Q provides improved rejection of spurious signals, resulting in improved performance. Additionally, the oscillator is well-suited for burst mode operation, since the output frequency can be maintained within a tight tolerance during operation.

Power Supply

The EG-2121CA 53.1250M-LHPAB oscillator operates with a supply voltage of 3.3V and consumes less than 300 mW of power. The oscillator provides high-stability tuning over a temperature range of –40°C to +85°C, and is capable of operating at a higher supply voltage (6V) if required. In addition, the oscillator features a soft start function, which allows the frequency to be accurately tuned even after the power supply is turned on.

Conclusion

The EG-2121CA 53.1250M-LHPAB oscillator is a high-performance, low-phase-noise oscillator well suited for a variety of commercial and industrial applications. It features a voltage-controlled oscillator (VCO) along with a PLL circuit to provide frequency tuning, phase accuracy, and stable reference voltage for the VCO. Additionally, the oscillator is designed to reduce power consumption and is well suited for burst mode operation.
