Abstract: A system and method of performing temperature compensation based on temperature of a crystal. An integrated circuit includes a clock circuit, a memory, an interface developing a sense voltage indicative of a temperature of the crystal, and a controller. The memory stores compensation values including nominal values based on a nominal third order polynomial that defines a nominal frequency versus temperature relationship of a crystal design representing multiple crystals, and a pair of adjustment values derived from two temperature-frequency error points. The controller determines a temperature value based on the sense voltage, calculates a frequency offset using the temperature value and the compensation values to solve a compensated third order polynomial defining a compensated frequency versus temperature relationship of the crystal, and adjusts a clock signal of the clock circuit using the frequency offset. A Wi-Fi device may be optimized for industrial IoT operating within an extended temperature range.
