ASTX-H12-12.000MHZ-T
Overview
The ASTX-H12-12.000MHZ-T is a 12 MHz Temperature Compensated Crystal Oscillator (TCXO) designed for applications requiring high precision in a compact 2.5mm x 2.0mm footprint. It provides an HCMOS output with a stable +/-2.5ppm frequency tolerance across a wide operating temperature range of -20C to +75C. Operating at 3.3V, this component includes an enable/disable function for power-sensitive designs.
Why Choose This Part
This TCXO offers superior frequency stability of +/-2.5ppm compared to standard crystal oscillators, making it ideal for narrowband communications. Its small 4-SMD package saves significant PCB real estate, while the integrated HCMOS buffer simplifies interface circuitry with most modern MCUs.
Applications
Key Specifications
Getting Started
Ensure a 0.01uF to 0.1uF bypass capacitor is placed as close as possible to the VDD pin (Pin 4) to minimize noise. When using the enable/disable function on Pin 1, verify the logic levels match your 3.3V system rail to avoid unintended tri-stating of the HCMOS output.
