Overview
The ABRACON CORPORATION ABLS-4.000MHZ-B2-T is a fundamental mode crystal oscillator designed to provide a stable 4.000MHz reference frequency. Its ±20ppm frequency tolerance ensures precise timing critical for digital signal processing and communication systems. A key design consideration when selecting this component is its 18pF load capacitance, which must be carefully matched with the external circuit’s parasitic capacitance to avoid frequency pulling and maintain optimal performance, a common trade-off in achieving high accuracy with surface-mount crystal units.
Key Features
- Frequency: 4.000 MHz
- Frequency Tolerance: ±20ppm
- Load Capacitance: 18pF
- ESR: 180 Ohms
- Operating Temperature: -20°C to 70°C
- Dimensions: 11.40mm x 4.70mm x 4.20mm (L x W x H)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Microcontroller clock generation for embedded systems
- Real-time clock (RTC) circuits in consumer electronics
- Low-speed data acquisition system timing
- Phase-locked loop (PLL) reference in basic communication modules
