Abracon O-C14AL NEL Low Phase Noise OCXO

Introduction

The Abracon O-C14AL is a low phase noise oven-controlled crystal oscillator (OCXO) designed for timing systems that require exceptional frequency stability and low jitter. Built around an SC-cut crystal and an internal temperature-controlled oven, it maintains a highly stable output across demanding operating environments.

Part Description

The O-C14AL NEL series is a compact OCXO family from Abracon intended for precision frequency-reference applications. Its internal oven regulates crystal temperature to minimize frequency drift caused by ambient temperature changes.

Key characteristics include:

• SC-cut crystal resonator for strong phase-noise performance
• Frequency stability of ±5 ppb from -40°C to +85°C
• Low phase noise for sensitive RF, communications, and measurement systems
• Approximately 65 mA steady-state current consumption
• Fast warm-up behavior for quicker availability of a stable timing reference
• Voltage-control capability for frequency trimming, calibration, or synchronization loops
• Sine-wave and CMOS/TTL output options
• Compact form factor compared with many traditional OCXO solutions
• Low-power operation for an oven-controlled oscillator

The device is especially useful where a standard crystal oscillator or TCXO cannot provide sufficient stability, phase-noise performance, or long-term timing consistency.

Applications

Potential applications for the O-C14AL include:

• Precision frequency references
• RF signal generators
• Wireless base stations
• Microwave and millimeter-wave local oscillators
• GPS/GNSS timing and synchronization receivers
• Network synchronization equipment
• Telecom timing cards
• Test and measurement instruments
• Spectrum analyzers
• Frequency counters
• Rubidium or atomic-clock disciplining circuits
• Clock-cleaning and jitter-sensitive digital systems
• High-performance data acquisition equipment
• Radar and electronic warfare subsystems
• Software-defined radio platforms
