Abstract: A frequency locked loop circuit, comprising an operational circuit, a first impedance circuit, a second impedance circuit, a switching circuit and a frequency generation circuit. The operational circuit is configured to output an operational signal according to a voltage difference between a positive terminal and a negative terminal. The switching circuit is configured to periodically conduct the negative terminal to one of the first impedance node and the second impedance node, and periodically conduct the positive terminal to the other one of the first impedance node and the second impedance node. The frequency generation circuit is configured to periodically sample the operational signal to generate a sample signal to generate a clock signal. An operational frequency of the operational signal is an integer multiple of a sampling frequency of the frequency generation circuit.

Abstract: A dual mode serial transmission apparatus and method for switching a mode thereof are provided. The dual mode serial transmission apparatus includes a first and second current sources, a first and second inverting circuits, a differential pair and a resistor string. The first inverting circuit receives a mode selecting signal or a first data transmission signal, the second inverting circuit receives the mode selecting signal or a second data transmission signal. First and second load terminals of the differential pair are respectively coupled to the first and second inverting circuits. A common terminal of the differential pair is coupled to the second current source. First and second differential input terminals receive the mode selecting signal or respectively receive the first and second data transmission signals. The resistor string is coupled in series between output terminals of the first and second inverting circuits.
