ECS-3225S25-100-EN-TR

Oscillators: ECS-3225S25-100-EN-TR

ECS-3225S25-100-EN-TR is a type of temperature compensated crystal oscillator (TCXO) for use as a local oscillator in both transmit and receive synthesizers of frequency hopping radios. This oscillator provides a better short-term stability due to its temperature compensated design which ensures it stays at the same output frequency at different temperatures. This is an important feature for applications such as military, wireless networks, aviation and satellite communications.

Application Field:

The ECS-3225S25-100-EN-TR is suitable for use in many frequency hopping, multi-channel radio systems, as well as in wireless LANs and cordless phones. Apart from this, it can also be used as a local oscillator for systems in other specialized fields, such as military radios, Satcom modems, wireless data links, AIS and marine communications, as well as various navigation applications. This type of TCXO also finds utility in professional radios, PMR446, DECT, and other applications requiring a highly temperature compensated oscillator.

Working Principle:

The ECS-3225S25-100-EN-TR uses a frequency control loop algorithm to actively monitor and adjust the output frequency in order to keep it stable and in tune. The device uses a temperature compensated resonator (TCXO) to ensure the frequency stays the same regardless of environmental conditions. The input voltage is constantly monitored and adjusted to ensure the frequency is within the specified limits. The unit is powered by a single voltage supply, typically 3.3V or 5V.

The ECS-3225S25-100-EN-TR also features a low glide voltage output which minimizes frequency variance when changing temperature. As the temperature changes, the device compensates for the changes by automatically altering the pull capacitance to minimize frequency variations. This ensures that the output frequency remains within the specified limits.

Conclusion

The ECS-3225S25-100-EN-TR temperature compensation crystal oscillator is a reliable and suitable device for many radio systems and communication applications that are sensitive to frequency variations due to temperature changes. The oscillator is capable of outputting a stable frequency with minimal variation, making it an ideal solution for applications where absolute stability is required.
