Abstract
Aspects of a method and system for an energy efficient temperature sensing crystal integrated circuit (TSCIC) are provided. In this regard, one or more circuits in a temperature sensing crystal integrated circuit (TSCIC) may be configured to control power consumption of the TSCIC. The one or more circuits in the TSCIC may comprise a memory and a crystal. The one or more circuits in the TSCIC may be operable to generate an indication of temperature of the crystal. The one or more circuits in the TSCIC may be configured to control a current supplied to the crystal within the TSCIC, wherein the configuring is based on phase noise requirements of a signal generated by the crystal. Generation of the temperature indication may be enabled or disabled. The enabling or disabling may occur based on a rate of change of a temperature in the TSCIC.
