    摘要: The present invention provides a transmission apparatus and a reception apparatus easy to sample data correctly by a clock in the reception apparatus. In a detection section 25 of a reception apparatus 20 n , based on data output from a sampler section 23, both or either of detection of a phase difference between data received by a data reception section 21 and a clock received by a clock reception section 22, and/or waveform distortion of this data is performed. A detection signal indicating a result of detection by the detection section 25 is transmitted to a transmission apparatus 10 by a detection signal transmission section 26. In the transmission apparatus 10, by a control section 15, based on the detection signal received by a detection signal reception section 14, both or either of control of adjustment of a phase between data transmitted by a data transmission section 11 and a clock transmitted by a clock transmission section 12, and/or adjustment of an amplitude of the data is performed.

    摘要: A video transmission device 10 has: a packer 11 which receives a video signal, a sync signal, and a data-enable signal, and generates a plurality of packet signals by packetizing the video signal and the sync signal based on the data-enable signal and according to the number of bytes of a packet corresponding to the number of gradation bits of the video signal; an encode unit 15 which generates a plurality of encoded packet signals by encoding the plurality of packet signals; and a serializer 14 which generates a serial packet signal by parallel-serial converting the plurality of encoded packet signals. The packer 11 generates a control signal including a pulse with a pulse width corresponding to the number of bytes of the packet, and the encode unit 15 subjects a portion of the packet signals corresponding to the pulse in the control signal from the packer, to an encode process which is different from a process for the other portion.

    摘要: In a reception apparatus 1, a multiphase sampling clock signal is generated by a sampling clock signal generation circuit 40, based on a clock signal which has been phase-adjusted by a phase adjustment circuit 50. The data of each of the bits of a serial data signal is sampled and output by a sampler block circuit 30n, with timing indicated by the sampling clock signal. The amount of phase adjustment of the clock signal in the phase adjustment circuit 50 is set such that the delay time from generation of the multiphase sampling clock signal in the sampling clock signal generation circuit 40 until indication of the sampling timing by the sampling clock signal in the sampler block circuit 30n is canceled.

    摘要: A clock data restoration device (1A) includes a sampler portion (11), a phase comparison portion (12), a drive portion (13), a charge pump (14), a capacitive element (15), a potential adjustment portion (16) and a voltage control oscillator (17). The phase comparison portion (12) outputs a signal (UP) that becomes a significant value when the phase of a clock (CKX) delays with respect to an input digital signal, and outputs a signal (DN) that becomes a significant value when the phase advances. The drive portion (13) increases or decreases a value δ to or from a variable Δ when the signals (UP) and (DN) become a significant value, and increases or decrease a value N to or from the variable Δ when the value of the variable Δ is equal to or more than +N or when the value of the variable Δ is equal to or less than -N, and signals (UPFRQ) and (DNFRQ) are output to the charge pump (14). The potential adjustment portion (16) increases or decreases a potential at a first end of a capacitive element (15) based on the signals (UP) and (DN).
