Keeping within drive level (DL) specification is critical to a crystal’s performance. Drive level refers to the power used to operate a crystal device. DL beyond maximum specification can push too much power through the crystal. When this happens, frequency tolerance, ESR and other performance parameters can be adversely affected, in some cases breaking the crystal and causing irreversible damage.
How do you ensure the crystal’s performance while preventing any damage? Epson’s Designer’s Guide to Common Considerations When Selecting a MHz Crystal outlines the typical range of drive level to maintain stable oscillation. From best practices to what to ask when talking to suppliers, we can help determine the best crystal for your product.
