Overview

The AOCJYR-10.000MHZ-M5625LF is a high-precision Oven Controlled Crystal Oscillator (OCXO) providing a stable 10MHz reference in a compact 9x7mm SMD package. It offers exceptional frequency stability of 25ppb over a wide temperature range from -40C to 85C. Operating at 3.3V with a CMOS output, this component is designed for systems requiring ultra-stable timing in space-constrained layouts.

Why Choose This Part

This OCXO combines the stability of traditional large-scale ovenized oscillators with a miniature 9.7mm x 7.5mm footprint. The 25ppb stability ensures minimal drift across the full industrial temperature range, while the 3.3V CMOS output allows for direct interfacing with modern FPGAs and MCUs without level shifting.

Applications

Base Station Timing
Provides the primary clock reference for cellular infrastructure and small cell synchronization.
GNSS Receivers
Enhances position accuracy and reduces time-to-first-fix (TTFF) in high-end GPS/GNSS navigation systems.
Test and Measurement
Serves as a local oscillator for portable frequency counters and signal analyzers.
Stratum 3 Clocking
Used in telecommunications networking equipment requiring high-precision holdover performance.

Getting Started

Ensure the PCB thermal relief is minimized around the component to allow the internal oven to stabilize efficiently. Use a low-noise 3.3V LDO to supply power, as the phase noise performance is sensitive to supply voltage ripple. Design the trace from the CMOS output to be as short as possible to maintain signal integrity at 10MHz.
