    摘要: A frequency synthesizer. The frequency synthesizer comprises a harmonic locked phase/frequency detector, a low pass filter, a voltage controlled oscillator, and a frequency divider. The harmonic locked phase/frequency detector receives a reference signal and a divided signal. The low pass filter is coupled to the harmonic locked phase/frequency detector. The voltage controlled oscillator is coupled to the low pass filter and provides an output signal. The frequency divider is coupled between the voltage controlled oscillator and the harmonic locked phase/frequency detector. Frequency of the divided signal is a harmonic frequency of the reference signal.

    摘要: A clock data recovery circuit. The clock data recovery circuit comprises a transmission line, a phase locked loop, a voltage controlled oscillator, a phase selector, and a D flip-flop. The transmission line receives an input signal. The phase locked loop receives the input signal via the transmission line and a reference clock and generates a first clock signal. The voltage controlled oscillator receives the input signal via the transmission line and a control voltage from an internal node of the phase locked loop, and generates a clock signal. The phase selector receives the input signal via the transmission line and the clock signal from the voltage controlled oscillator, and generates a clock output signal. The D flip-flop receives the input signal via the transmission line and the clock output signal, and generates a data output signal.

    摘要: An adapter for antenna on a mobile phone basically is a main body associated with an adapting tube and a cover. A receiving recession is provided between the main body and the cover for containing a wave eliminating plate. The adapting tube is used for fitting with the antenna. The main body has a plurality of through holes for being passed by the rubber forming the adapting tube. The rubber overflowed from each through hole is associated with each other and constitutes a fixing part such that the adapting tube is integrated with the main body. The adapting tube is made of highly elastic and non-brittle rubber and has features such as flexible, free from aging, and durable. Therefore, the adapter is possible to sleeve with any size of antenna on a mobile phone firmly without a phenomenon of being loosened due to elastic fatigue and being damaged due to brittleness after using a period of time.
