20100054387 | SYNCHRONIZING DEVICE FOR USB REAL-TIME AUDIO DATA TRANSMISSION - The present invention discloses a synchronizing device for real-time USB audio data transmission, comprising: a first adder unit, a start-of-frame countdown unit, a phase-locked loop circuit, a frequency divider, a second adder unit, a third adder unit, a fourth adder unit, a frame calibrating register unit, a calibrating mapping unit and a calibrating pulse generating unit. A start-of-frame token sent by the USB host is used as a 1-ms reference cycle so that a high-frequency clock passes through the frequency divider to issue a first clock. The first clock signal has a constant clock number in a USB start-of-frame. The absolute time is automatically adjusted according to the duration of a previous start-of-frame. Therefore, asynchronicity of data transmission between the USB host and external devices can be overcome. | 03-04-2010 |
20100085072 | DETECTION CONTROL CIRCUIT FOR ANTI-LEAKAGE - The present invention discloses a detection control circuit for preventing a leakage current, which comprises a register unit comprising a clock signal input terminal for receiving a clock signal; a reset signal input terminal, for receiving a reset signal; a signal generating terminal, for generating a logic signal; and a logic gate, coupled to said register unit, comprising a first signal input terminal for receiving said logic signal; a second signal input terminal for receiving a control signal; and a signal output terminal, for outputting an output signal according to said logic signal and said control signal; wherein said control signal controls said logic gate so as to keep said output signal to be in a fixed state which detects a leakage current in an integrated circuit due to the process flaw. | 04-08-2010 |
