Title:
DATA TRANSMISSION-RECEPTION APPARATUS AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/085845
Kind Code:
A1
Abstract:
Provided is a data transmission-reception apparatus that, regardless of characteristics of a transmission line and a transmission side, can maximize a set-up time and a hold time of a flip-flop when resynchronization is performed and a data signal is determined.
The data transmission-reception apparatus is provided with: a data generation unit 4 that generates a clock signal and a data signal that is synchronized with the clock signal; a data synchronization unit 8 that receives the clock signal and the data signal transferred by a data transfer unit 11, and that determines whether the data signal is at an H level or an L level on the basis of a changing edge of the clock signal; output units 9 and 10 that detect the absolute value of a phase error between changing edges of the clock signal and the data signal transferred by the data transfer unit 11, and that output a jitter signal based on the absolute value; a control unit 7 that outputs a waveform control signal for adjusting a high-frequency enhancement level of the data signal generated by the data generation unit 4 so that the jitter signal output by the output units 9 and 10 is minimized; and an enhancement processing unit 6 that performs high-frequency enhancement processing on the data signal on the basis of the waveform control signal output by the control unit 7.
