Abstract
The present invention relates to an oscillating apparatus. The oscillating apparatus includes a biasing circuit, a multi-vibrator, a detecting circuit, and a selecting circuit. The biasing circuit is for generating a bias signal, wherein the biasing circuit includes a connecting port for using an impedance device to control an oscillating frequency or for directly connecting to external clock source as a reference clock. The multi-vibrator coupled to the biasing circuit for generating the oscillating frequency according to the quantity of the biasing signal. The detecting circuit coupled to the connecting port for generating a detecting signal whether the connecting port is coupled to the impedance device or the external clock source. The selecting circuit includes an AND gate coupled to the multi-vibrator and the selection signal and an OR gate coupled to the AND gate and the connecting port.
