Overview

The AOCJY-10.000MHZ-E-SW is a high-precision Oven Controlled Crystal Oscillator (OCXO) providing a stable 10 MHz sine wave output. It features an integrated heating element that maintains a constant internal temperature, achieving a frequency stability of +/-10ppb across a -20C to 70C range. This component is designed for 3.3V systems and offers excellent phase noise performance of -150dBc/Hz at 10kHz offset.

Why Choose This Part

The OCXO architecture delivers frequency stability that is orders of magnitude better than standard TCXOs, maintaining +/-10ppb accuracy despite ambient temperature fluctuations. Its sine wave output minimizes harmonic distortion, while the surface-mount package facilitates automated assembly in compact industrial designs.

Applications

Base Station Timing
Providing a stable reference clock for cellular base stations and small cells to ensure precise synchronization.
Network Switches and Routers
Acting as a master clock in high-speed networking equipment to reduce jitter and packet errors.
Precision Instrumentation
Used as the internal timebase for frequency counters, spectrum analyzers, and synthesized signal generators.
GPS Disiplined Oscillators (GPSDO)
Serving as the local oscillator that is disciplined by GPS pulse-per-second signals for ultra-high accuracy.

Getting Started

When designing the PCB, provide a dedicated 3.3V power plane and ensure the VCOCXO is isolated from high-heat components and airflow to maintain thermal stability. A warm-up period of several minutes is typically required after power-on to reach the specified stability. Use high-quality decoupling capacitors near the power pins to minimize phase noise degradation.
