Abstract
A portable control apparatus includes a driver, a baseband controller, and a crystal oscillator. The driver includes an oscillating circuit that generates a feedback signal. The baseband controller coupled to the driver receives the feedback signal, and outputs a calibrating signal to the driver according to the feedback signal. The crystal oscillator coupled to the baseband controller generates an accurate output frequency for operating the baseband controller.
