  • Patent number: 7796063
    Abstract: A transmission circuit includes a serial clock generator, a serializer and a transmission clock generator. The serial clock generator generates a serial clock. The serializer serializes N-bit parallel data to N-bit serial data in synchronization with the serial clock. The transmission clock generator receives the serial clock to generate a transmission clock that has a same delay as the N-bit serial data, and the data transmission circuit simultaneously transmits the N-bit serial data and the serial clock.

  • Patent number: 7719321
    Abstract: A short pulse rejection circuit may include an edge detector, a filter circuit, a comparison circuit, and a gating circuit. The edge detector may delay an input signal to generate a delayed input signal, and detect an edge of the input signal to generate an edge detection signal. The filter circuit may perform a low pass filtering on the edge detection signal to generate a first signal. The comparison circuit may compare the first signal with a reference voltage. The gating circuit may gate the delayed input signal based on an output signal of the comparison circuit. Therefore, the short pulse rejection circuit may have a sufficient setup/hold time margin of a flip-flop, and may sample an input signal even when a state of the input signal does not change during an initial operation.
