Oscillators

Oscillators are devices that generate a signal with a predictable and precise frequency. These signals have wide applications as they can be used in measuring and controlling in many industrial control systems. Oscillators are used to produce a continuous signal, meaning they don’t have any distinct start or stop. One example of an oscillator is the ECS-2520S18-050-EN-TR.

Application Field

The ECS-2520S18-050-EN-TR is a high-performance, multi-output oscillator. It is designed for synchronous and asynchronous networking applications in telecom, industrial, medical and aerospace applications. It provides four outputs of 8 kHz, 16 kHz, 255 kHz and 255 kHz with a frequency stability of between 0.3 ppm (2x105). It is designed for a wide range of operating voltages with a supply voltage range of 3.25V to 5.5V and a temperature range of -20 to +70°C. This oscillator is ideal for applications where multiple frequency sources are needed such as clock recovery for synchronous data transmission and providing clocking signals for digital signal processors and controllers. It is also used in clock recovery for synchronous data transmission.

Working Principle

The core of the ECS-2520S18-050-EN-TR is based on a resonator. This resonator creates electrical signals in a frequency proportional to the capacitance and inductance ratio in the circuit. The resonator consists of an inductor, two capacitors and two resistors. The combination of these components creates a series resonance circuit with a resonance frequency determined by the ratio of the inductive and capacitive reactance of the components. The circuit is configured in such a way that the resonant frequency is maintained even when the supply voltages change slightly. This is done by placing the tuning components in the opposite configuration and is called an autotune-type oscillator.

The ECS-2520S18-050-EN-TR is a temperature compensated oscillator (TCXO) and employs two temperature sensors, connected to the positive and negative supply rails. The temperature sensors adjust the frequency as the environmental temperature changes, thus providing excellent temperature stability. The TCXO maintains the frequency within typically 0.3 ppm (2x105) over the entire operating temperature range of -20 to +70°C. This ensures that the frequency of the device stays consistent in applications where temperature is expected to change.

The ECS-2520S18-050-EN-TR is a low-power device, with a maximum current consumption of 17 mA. This makes it ideal for portable and embedded applications where power consumption is a concern. It is also a compact device, with a small footprint and low profile, making it easy to include in systems.Due to these features and its multiple frequency outputs, the ECS-2520S18-050-EN-TR oscillator is a highly versatile solution for a wide range of applications.
