ECS-8FM-120-TR

Oscillators are electrical circuits that generate regularly repeating electrical signals. Such signals are used to create musical tones, carry data in communications systems, control electricity in power grids, and many other applications. The particular oscillator being discussed in this article is the ECS-8FM-120-TR, which is a type of voltage-controlled oscillator (VCO).

Voltage-controlled oscillators are systems where an electrical signal is used to control the frequency of an output waveform. The main components of a VCO are a voltage-controlled amplifier (VCA), a tuned circuit, and usually a buffer. The VCA provides the control signal, which can be either an alternating current (AC) or direct current (DC) signal. The tuned circuit, typically made up of an inductor and capacitor, is then used to shape or modulate the output waveform. Finally, the buffer provides isolation between the VCO and the control signal, and also allows the output waveform to be used in other circuits.

The ECS-8FM-120-TR is a VCO designed to provide radio-frequency (RF) signals for applications such as wireless communications, ultrasound transducers, radar, and synthesized music applications. The device operates on a frequency range of 8 to 120MHz and has a tuning resolution of 200kHz. The linearity of the tuning characteristic is 2.5% over the full temperature range of -40°C to +110°C. The signal-to-noise ratio is typically 93dBc/Hz at a 100kHz offset for an input voltage of 0V to 5V, making the ECS-8FM-120-TR well suited for a wide range of communication systems.

The device has two main modes of operation, linear and swept frequency. Linear mode is used when the frequency is set to a specific value, while swept frequency mode is used when the frequency is changed by an input control signal in order to determine the resonance frequency of the device. In linear mode, the nominal output power is +10dBm, while in swept frequency mode it is +5dBm. The device also has a 0.6V p-p output, which is used to inform other circuits when the desired frequency has been reached.

The ECS-8FM-120-TR is a highly versatile VCO that can be used in a wide range of applications. Its high linearity and signal-to-noise ratio make it well suited for communication systems, ultrasound transducers, radar, and synthesized music applications. Its ability to operate over a wide temperature range also makes it suitable for use in extreme environments. The device’s two modes of operation, linear and swept frequency, make it even more versatile, allowing for a range of applications from frequency synthesis to filtering.
