AOCJYR-20.000MHZ-M5627LF
Overview
The AOCJYR-20.000MHZ-M5627LF is a high-precision Oven Controlled Crystal Oscillator (OCXO) designed to provide an exceptionally stable 20 MHz frequency reference. It features a +/-20ppb frequency stability over a wide temperature range of -40 to +85 degrees Celsius, making it suitable for demanding timing applications where standard TCXOs are insufficient.
Why Choose This Part
This OCXO offers a remarkable frequency stability of +/-20ppb in a compact 9.7 x 7.5 mm surface-mount package. Operating at 3.3V with an LVCMOS output, it integrates easily into digital systems while maintaining low power consumption for its class, with a maximum supply current of 122mA.
Applications
Key Specifications
Getting Started
When designing with this component, ensure the PCB layout includes a dedicated ground plane and minimal trace lengths for the 20 MHz LVCMOS output to prevent EMI. Allow for a warm-up period after power-on to reach the specified stability as the internal heater stabilizes the crystal temperature. Decouple the 3.3V supply with a 0.1uF and 10uF capacitor pair located as close to the VDD pin as possible.
