Abstract:
An oven controlled crystal oscillator consisting of heater-embedded ceramic package includes a substrate, a crystal package, a crystal blank, a metal lid, a first IC chip, and a cover lid. The crystal package is mounted on the substrate, and a central bottom of the crystal package is provided with the first IC chip. The crystal blank is mounted in the crystal package and sealed by the metal lid. The crystal package has an embedded heater layer establishing a symmetric thermal field with respect to the first IC chip and the crystal blank. Alternatively, a heater-embedded ceramic carrier substrate is arranged between the first IC chip and the crystal blank to establish a symmetric thermal field with respect to the first IC chip and the crystal blank. The cover lid is combined with the substrate to cover the crystal package and the metal lid.

Claim (Index 13):
The oven controlled crystal oscillator according to  claim 1 , wherein said heater-embedded crystal ceramic package comprises a ceramic carrier substrate, and a heater-embedded crystal package having said first embedded heater layer mounted on said ceramic carrier substrate.
