Double oven ocxo

Double oven ocxo, ambient ±20ppb -40~85℃
referenced to (Fmax+Fmin)/2, Sinewave output.

Product Overview

The dual-oven OCXO (Model: XTALOCXO-3627-10M-5V-SWD) delivers ultra-high frequency stability and exceptional phase noise performance through its advanced dual-chamber thermal control system. Designed for mission-critical applications, this oscillator combines nested ovenized insulation with precision analog/digital circuitry to achieve ±0.1 ppb frequency stability over extended temperature ranges (−40°C to +85°C).

Key advantages

1. High -stable temperature frequency stability: <±0.1ppb

2. Dual-Oven Temperature Control: Two-stage thermal regulation minimizes ambient temperature effects, ensuring <5E-12@1s short-term stability.

3. Low Phase Noise: Optimized for RF and timing systems, with typical phase noise −150 dBc/Hz @ 1 kHz offset (10 MHz).

4. Aging Resistance: High-reliability crystal design guarantees <±0.1ppb/Day aging rate.

5. Ideal for 5G base stations, satellite navigation (GNSS), military communications, and quantum technology, this OCXO sets the benchmark for precision timing in harsh environments.
