Oscillators

Oscillators are electronic circuits used to form repetitive wave signals. An oscillator generates an alternating current by repeatedly charging and discharging capacitors within the circuit, as determined by an active component such as a transistor. They can be used to create a wide range of signals, from very simple sinusoidal patterns to complex modulation signals. The main application of an oscillator is to form a clock signal which acts as an internal timing mechanism for digital systems, providing synchronization for circuit components. Oscillators are also widely used within audio equipment, where they are used to create the sine wave signal which drives loudspeakers.

EG-2102CA 155.5200M-PGRNB application field and working principle

The EG-2102CA 155.5200M-PGRNB oscillator is a high-precision, ultra-low power quartz oscillator. It is ideal for applications requiring very low power consumption, high stability, and low jitter. The oscillator has an extremely low Phase Noise of -123 dBc/Hz at 1kHz and an excellent frequency tolerance of 0.3ppm. This makes it ideal for use in applications requiring high precision and frequency stability, such as test and measurement, medical, and telecommunications. The EG-2102CA is also RoHS compliant and can be used in lead-free systems.

The working principle of the EG-2102CA 155.5200M-PGRNB oscillator is based on a quartz crystal, which has a natural resonant frequency. An alternating current is applied to the crystal to oscillate at its natural frequency. An internal circuit then amplifies and shapes the oscillations and the output signal is taken from a buffer amplifier which provides a clean and stable signal. The oscillator is adjusted to the required frequency by placing a dielectric layer between the crystal and the ground plane, which alters its capacitance and thus the frequency of the oscillated current.

The EG-2102CA 155.5200M-PGRNB oscillator has a wide range of applications. It is typically used in precision timing applications, such as frequency stabilization and signal synchronization in radio communications, satellite navigation systems, GPS systems, and medical applications. It is also used in high precision data acquisition and control systems, particularly those requiring low jitter performance, such as automotive motion control systems.
