摘要： Disclosed herein is a temperature compensated crystal oscillator. The temperature compensated crystal oscillator has first and second layered structures, an IC chip, a crystal vibrating chip, a resin mold portion and a metal cover. The first layered structure is comprised of at least one layer and provided with a cavity formed therein. The second layered structure is arranged on the upper surface of the first layered structure, comprised of at least one layer, and provided with a cavity formed in a region not overlapped with the cavity of the first layered structure. The IC chip is inserted into the cavity of the first layered structure. The crystal vibrating chip is inserted into the cavity of the second layered structure. The resin mold portion is formed by charging resin into the cavity of the first layered structure accommodating the IC chip to form its bottom surface level with the lower surface of the first layered structure. The metal cover is arranged on the upper surface of the second layered structure for covering the cavity formed of the second layered structure.

摘要： The present invention relates to a multiple output crystal oscillator having a plurality of output terminals for implementing multiple output and Integrated Circuit (IC) chips. More particularly, the crystal oscillator comprises a crystal resonator, a first IC chip having an oscillating circuit block and a frequency-adjusting circuit block, a second IC chip having an output-adjusting block, and a substrate structure for mounting said first and second IC chips, wherein said output terminals include a basic output terminal for outputting the oscillating signal from said first IC chip and at least one additional output terminal for outputting at least one wave form-adjusted oscillation signal from said second IC chip. In the present invention, said basic output terminal is placed on one of four underside corners of said substrate, and said additional output terminal is placed on the portion of the underside except the corners.
