Temperature stability si5351

Post by kenndaniel »

I'm using an si5351 on a balloon project that will get down to about -20c. What is the temperature drift characteristics of the crystal that is mounted on the si5351 break out board?

It will probably be between -65ppm and -77ppm. The typical drift for AT-cut crystals is a quadratic function of temperature: -0.035 x (25-T)^2 +/-6ppm.
