ABCM-51 Disciplined OCXO

Introduction

ABCM-51 GPS disciplined OCXO is a crucial component in systems where precise and reliable timing is critical, leveraging the strengths of both GPS technology and high-quality crystal oscillators.
By using a GPS/GNSS-disciplined oven-controlled crystal oscillator (GPSDO) offers several advantages, particularly in applications that require high precision and accuracy in timing and frequency control.

GNSS disciplined OCXO (Oven-Controlled Crystal Oscillator) is a highly stable and precise timing device that uses 1PPS signal from GPS satellites to discipline and correct the frequency of an OCXO. This results in extremely accurate and stable timing. Here are the main applications of GNSS disciplined OCXOs:

Key markets are:

Telecommunications

  • Base Stations: Provide accurate timing for synchronization of cellular networks, ensuring seamless handoffs and efficient spectrum usage.

  • Backhaul Networks: Used in synchronization of data transmission between base stations and the core network.

  • Time Division Multiplexing (TDM) Systems: Ensure precise timing in multiplexed communication systems.

Broadcasting

  • TV and Radio Transmitters: Synchronize the transmission of audio and video signals to prevent broadcast delays and maintain quality.

  • Satellite Broadcasting: Provide timing synchronization for satellite uplink and downlink operations.

Data Centers and Network Infrastructure

  • Network Time Protocol (NTP) Servers: Provide accurate timing to networked devices for synchronization and time-stamping.

  • Precision Time Protocol (PTP) Systems: Ensure high precision timing in financial trading systems, where microsecond accuracy is crucial.

Power Distribution

  • Smart Grid Applications: Synchronize the timing of power generation, distribution, and consumption data for efficient energy management.

  • Grid Monitoring and Protection: Provide accurate time-stamping of events for fault detection and resolution.
