Abstract
A crystal reference (100) comprises a crystal element (102) integrally housed with a memory device (108), and is coupled to the memory device through an anti-resonant network (110). The network is designed such that it presents a high impedance at the natural frequency of the crystal element. Temperature performance information for the particular crystal element is stored in the memory device, and is accessed via terminal (112) using a single wire interface protocol.
