OX-500 is a fast warm-up TCXO replacement for better short term stability from Vectron with frequency stability of -100 +100 ppb -20 … +70°C (referenced to +25°C) and a temperature range of -40… +85°C.
The OX-500 is an oven‑controlled crystal oscillator (OCXO) designed for military communication equipment and test equipment, offering fast warm‑up and high short‑term stability. It is supplied in a 4‑pin package and can replace TCXOs in applications requiring improved frequency stability.
The document lists detailed electrical parameters, temperature ranges, pin assignments, and ordering codes, along with notes on supply voltage, power consumption, phase‑noise performance, and mechanical dimensions.
