When selecting a crystal, it’s important to consider the location of the crystal within the design. Ambient crystal temperature within the device could be much higher than the overall system operating temperature. If a crystal is used in an environment that exceeds its operating temperature, errors may occur that could impact performance.
These errors have prompted change in the industry. For example, it’s become more common to extend a crystal’s operating temperatures to support industrial and automotive applications. Epson’s Designer’s Guide to Common Considerations When Selecting a MHz Crystal breaks down these changes. From crystal manufacturers accommodating for increased operating temperatures for different industries to understanding the crystal’s temperature characteristic, we can help determine the crystal that fits your product’s needs.
