Transmission device, reception device, transmission-reception system, and image display system

摘要

Reception devices 201 to 20N are arranged one-dimensionally in this order. The reception device 20n has a data input buffer 21, a first clock input buffer 221, and a first clock output buffer 231. The first clock input buffer 221 buffers a clock input to the first clock terminals P21 and P22, and outputs it to the first clock output buffer 231. The first clock output buffer 231 buffers a clock input from the first clock input buffer 221 and outputs it from the second clock terminals P31 and P32. The data input terminals P11 and P12 are located between the first clock terminal and the second clock terminal.

主权项

1. A transmission device which transmits a clock and data to each of N reception devices arranged one-dimensionally, comprising:
data output terminals which output data individually to each of the N reception devices, and a first clock output terminal which outputs a common clock to a reception device of p reception devices arranged successively among the N reception devices, the reception device successively outputting the common clock to the remainder of the p reception devices in a serial fashion, and a control unit which adjusts a phase difference between data output from the data output terminals corresponding to each of the p reception devices and a clock output from the first clock output terminal, wherein the data output terminals corresponding to each of the N reception devices are arranged in a same order as the order of arrangement of the N reception devices, the first clock output terminal is located at a first direction side of all the data output terminals corresponding to each of the p reception devices, with no data output terminals interposed in-between that correspond to reception devices other than the p reception devices among the N reception devices, and N and p are integers equal to or larger than two.
