Patent number: 11949378Abstract: A crystal oscillator and an oscillating device are provided. The crystal oscillator includes a resonator, a low-thermal conductivity glue, an integrated circuit chip, and a heating element. In the resonator, a crystal blank is hermetically encapsulated. The low-thermal conductivity glue wraps the resonator to suppress temperature variation in the resonator. The integrated circuit chip is disposed below the resonator, and the heating element is configured to supply heat to the resonator.Type: GrantFiled: August 29, 2022Date of Patent: April 2, 2024Assignee: TXC CorporationInventors: Erh-Shuo Hsu, Wan-Lin Hsieh

Patent number: 11699990Abstract: An oscillating device includes a first quartz crystal resonator, a driving circuit, a first waveform adjustment circuit, and at least two second quartz crystal resonators. The first quartz crystal resonator has a first resonant frequency. The driving circuit, coupled to the first quartz crystal resonator, drives the first quartz crystal resonator to generate a first oscillating signal having the first resonant frequency. The second quartz crystal resonators, coupled in parallel and coupled to the driving circuit and the first quartz crystal resonator, have a second resonant frequency and receive and rectify the first oscillating signal to generate a second oscillating signal having the second resonant frequency. The first waveform adjustment circuit, coupled to the second quartz crystal resonators, receives the second oscillating signal and adjusts the second oscillating signal to generate a first waveform adjustment signal.Type: GrantFiled: August 29, 2022Date of Patent: July 11, 2023Assignee: TXC CORPORATIONInventors: Yu-Liang Chen, Chih-Hsun Chen, Wan-Lin Hsieh, Erh-Shuo Hsu, Sheng-Hsiang Kao

Patent number: 11469738Abstract: An oscillating device includes a first quartz crystal resonator, a driving circuit, a first buffer, an attenuator, a second quartz crystal resonator, and a second buffer. The first quartz crystal resonator and the second quartz crystal resonator respectively have a first resonant frequency and a second resonant frequency. The driving circuit drives the first quartz crystal resonator to generate a first oscillating signal having the first resonant frequency. The first buffer generates a first clock signal in response to the first oscillating signal. The attenuator reduces the wave swing of the first clock signal to generate an attenuated signal. The second quartz crystal resonator rectifies the attenuated signal to generate a second oscillating signal having the second resonant frequency. The second buffer generates a second clock signal in response to the second oscillating signal.Type: GrantFiled: July 19, 2021Date of Patent: October 11, 2022Assignee: TXC CORPORATIONInventors: Wan-Lin Hsieh, Yu-Liang Chen, Erh-Shuo Hsu, Chih-Hsun Chen, Sheng-Hsiang Kao

Patent number: 10855289Abstract: An oven controlled crystal oscillator consisting includes a substrate, which includes a substrate, at least one base, a crystal blank, a first cover lid, an IC chip, a heat-insulating adhesive, a heater, and a second cover lid. The top of the base is provided with a cavity, and the top of the base is connected to the substrate through conductive wires without using solder. The crystal blank is mounted in the cavity. The first cover lid seals the cavity. The IC chip is mounted on the bottom of the base. The base is mounted on the substrate through the IC chip and the heat-insulating adhesive, and the IC chip is mounted to the bottom of the base. Alternatively, the IC chip and the base are horizontally arranged. The second cover lid is mounted on the top of the substrate.Type: GrantFiled: November 7, 2019Date of Patent: December 1, 2020Assignee: TXC CorporationInventors: Wan-Lin Hsieh, Erh-Shuo Hsu, Shao-Po Sun, Sheng-Hsiang Kao, Yu-Shun Yen
