Abracon O-C20AA-U-BSLM-100.000MHz Precision OCXO

Introduction

The Abracon O-C20AA-U-BSLM-100.000MHz is a high-performance oven-controlled crystal oscillator (OCXO) designed for applications that require an exceptionally stable and clean 100 MHz reference clock. Its SC-cut crystal architecture, sine-wave output, and compact 20 mm × 20 mm package make it suitable for demanding timing, measurement, and communications systems.

Part Description

The O-C20AA series is a precision OCXO from Abracon that uses an internal temperature-controlled oven to maintain crystal operation at a stable temperature. This minimizes the frequency variation normally caused by changing ambient conditions.

This 100 MHz model provides typical frequency stability of ±50 ppb and low first-year aging of approximately 0.2 ppm. It is also designed for ultra-low phase noise, with a maximum phase-noise specification of -175 dBc/Hz at a 100 kHz offset. The sine-wave output is well suited for RF, instrumentation, clock-generation, and frequency-reference circuits where signal purity is important.

Key characteristics include:

• Nominal output frequency: 100 MHz
• Oscillator type: Oven-controlled crystal oscillator (OCXO)
• Crystal type: SC-cut crystal
• Output waveform: Sine wave
• Typical frequency stability: ±50 ppb
• Phase noise: Up to -175 dBc/Hz at 100 kHz offset
• First-year aging: Approximately 0.2 ppm
