DIP OCXO

The OCXO (Oven Controlled Crystal Oscillator), to make the frequency accurate by keeping the oscillator at a fixed temperature. It is one of the most accurate Oscillator in the world. This type of Oscillator is often used in base station applications, whether it is 4G or 5G base stations. The most accurate specifications can reach ±10ppb.
