ECX-H35CM-25.000

Oscillators are electronic circuits used to generate a periodic, steady-state waveform, such as a sine wave or a square wave. They consist of two main elements: a source of electrical energy and a circuit component that uses the energy that it is supplied with to create a signal. The ECX-H35CM-25.000 oscillator is one such device, and its application field and working principle will now be discussed.

The ECX-H35CM-25.000 is a surface-mount oscillator that produces an output frequency of 25 MHz. It is typically used in application that require a stable clock frequency such as timing systems, frequency synthesizers, clocks and counters. The advantage of the ECX-H35CM-25.000 over other oscillators is that it can operate at a wide range of dynamic power supply, from 1.2 to 3.6 volts. This makes it suitable for a variety of applications.

The ECX-H35CM-25.000 oscillator consists of a quartz crystal that acts as the frequency-determining element, and its electrical behavior has been chosen to be a function of the crystal\'s movement. It also contains an amplifier and an IF filter to select the frequency, an OP amp to provide the output, and a PIN diode in the feedback loop to ensure that the oscillation stops should the amplitude of the oscillation reach a certain level, in order to prevent overshoot and ringing.

The working principle of the ECX-H35CM-25.000 oscillator is relatively simple. The quartz crystal is effectively a switch that closes and opens a circuit. When the crystal is in the open state, no oscillation occurs. However, when the crystal is closed, a signal is produced and this is amplified by the amplifier, filtered by the IF filter to select the output frequency, and then passed through the OP amp to create the output. This output is then constantly monitored for changes in amplitude, and if the amplitude rises above a certain level, the PIN diode is activated and the oscillation is terminated.

In summary, the ECX-H35CM-25.000 oscillator is a highly reliable, temperature stable device that is suitable for a range of uses. It consists of a quartz crystal as the frequency-determining element, an amplifier, an IF filter, an OP amp, and a PIN diode in the feedback loop. When the crystal is closed, a signal is produced, which is then amplified, filtered and passed through the OP amp to produce the output.
