Abstract: The present invention relates to an oscillating device, which comprises a driving module and an oscillating module. The driving module is used for producing a first driving voltage and a second driving voltage. The oscillating module comprises a first symmetric load circuit, a second symmetric load circuit, and a bias circuit. The first symmetric load circuit and the second symmetric load circuit produce a bias according to the first driving voltage. The bias circuit produces a bias current according to the second driving voltage. The oscillating module produces an oscillating signal according to the first driving voltage and the bias current, where the bias current is proportional to the bias. Thereby, by making the driving signal produced by driving module proportional to the bias of the oscillating module, simple compensation for temperature and process can be performed. Thereby, the frequency can be tuned using a few calibration bits.

Abstract: The present invention relates to a transmission interface device capable of calibrating the transmission frequency automatically, which comprises a clock generating unit, a data transmission unit, and a control unit. The clock generating unit is used for generating an operating clock, which determines a transmission frequency. The data transmission unit is used for connecting to a host and transmitting a plurality of data to the host or receiving the plurality of data from the host according to the operating clock. When the host or the data transmission unit detects transmission errors in the plurality of data, the host or the data transmission unit generates an error handling. The control unit generates an adjusting signal according to the error handling and transmits the adjusting signal to the clock generating unit for adjusting the transmission frequency of the operating clock.
