ASTX-H11-26.000MHZ-T
Overview
The ASTX-H11-26.000MHZ-T is a Temperature Compensated Crystal Oscillator (TCXO) that provides a stable 26 MHz reference clock with HCMOS output. It operates from a 3.3V supply and maintains a tight frequency stability of +/-2.5ppm across a temperature range of -30degC to 75degC. Housed in a compact 3.2mm x 2.5mm surface-mount package, it is designed for applications requiring higher precision than standard crystal oscillators.
Why Choose This Part
This TCXO offers a high frequency stability of +/-2.5ppm, which is significantly better than standard SPXOs. Its low current consumption of 5.5mA maximum makes it suitable for power-sensitive designs, while the integrated tri-state enable/disable function allows for easy power management and bus sharing.
Applications
Key Specifications
Getting Started
To integrate this component, ensure the 3.3V supply is properly decoupled with a 0.1uF ceramic capacitor placed close to the VDD pin. The HCMOS output is designed to drive a 15pF load; excessive trace capacitance should be avoided to maintain signal integrity. Verify that the enable pin (Pin 1) is pulled high for normal operation or low to enter a high-impedance standby mode.
