Working principle

In the CMX309FLC3.072M-UT, there is a temperature-compensated crystal oscillator (TCXO) to generate an accurate signal for timing. The TCXO is a quartz crystal that is stabilized by temperature compensating circuitry. This circuitry compensates for the physical change of the quartz when subjected to varying temperatures, resulting in a more accurate output signal.

Once the TCXO is stabilized, the signal is amplified and divided down, generating a square wave at the desired frequency. The square wave is then sent to a synchronous emitter coupled logic (ECL) buffer. This buffer outputs a clean, low jitter signal.

The TCXO is an ultra-stable reference oscillator giving stability for long-term holdover, making it a perfect choice for systems where high accuracy must be maintained over time. By using the CMX309FLC3.072M-UT in product designs, engineers can reduce system power consumption and still maintain high-performance without sacrificing accuracy.
