Abstract
Aspects of a method and system for a temperature sensing crystal Integrated circuit with digital temperature output are provided. In this regard, an indication of temperature may be generated in an integrated circuit (IC) comprising a memory, a crystal or crystal oscillator, and at least a portion of an analog-to-digital converter. The temperature indication may be digitized via the analog-to-digital converter. Operation of one or more circuits may be controlled based on the digital temperature indication. The digital temperature indication may be communicated over a communication bus. An analog portion of the analog-to-digital converter may be integrated in the IC and may comprise, for example, a delta-sigma modulator. A digital portion of the analog-to-digital converter may be external to the IC and may comprise, for example, a digital filter.
