Overview

The LFOCXO063815B is a high-precision 10 MHz Oven Controlled Crystal Oscillator (OCXO) featuring a Voltage Control (VC) function. It provides a sine wave output and operates on a 3.3V supply, offering exceptional frequency stability of +/-1ppb for timing-critical applications. This module is housed in a 36.20mm x 27.20mm through-hole package designed for robust performance in demanding environments.

Why Choose This Part

This OCXO offers extreme frequency stability of +/-1ppb, which is several orders of magnitude better than standard TCXOs. The sine wave output reduces harmonic distortion, while the integrated voltage control allows for fine frequency tuning to compensate for long-term aging or to lock to an external reference.

Applications

Cellular Base Stations
Provides the ultra-stable clock reference required for synchronizing high-speed telecommunications infrastructure.
Precision Instrumentation
Acts as a stable timebase for frequency counters, spectrum analyzers, and other high-end laboratory equipment.
Network Synchronization
Ensures precise timing in PTP (IEEE 1588) and Synchronous Ethernet (SyncE) hardware.
Satellite Communications
Delivers a low-phase-noise reference for RF up/down conversion in ground station equipment.

Getting Started

When integrating this module, ensure the PCB layout includes a solid ground plane and thermal isolation from heat-generating components to maintain its high stability. Provide a clean, low-noise 3.3V power supply capable of handling the initial warm-up current. Calibration can be performed by applying a control voltage to the VC pin as specified in the IQOV-164-4 footprint documentation.
