| 20100120383 | DIFFERENTIAL OUTPUT CIRCUIT AND COMMUNICATION DEVICE - A differential includes first and second current mirror circuits that provide the gates of slave transistors with gate voltages of master transistors via a voltage follower where a slew rate at a rise time is equal to a slew rate at a fall time. Thus, when the master current is increased or decreased, an incremental change in slave current and a decremental change in slave current are symmetrical with each other. The use of such current mirrors in a differential manner leads to no generation of common mode noise even in these changes. | 05-13-2010 |

When an HDMI (R) source performs bidirectional IP communication with an HDMI (R) sink using a CEC line and a signal line, a switching control unit controls a switch so that, when data is transmitted, the switch selects a constituent signal forming a differential signal output from a converting unit and, when data is transmitted, the switch selects a constituent signal forming a differential signal output from a receiver. When bidirectional communication is performed using only the CEC line, the switching control unit controls the switch so that the CEC signal output from the HDMI (R) source or the receiver is selected. The present invention is applicable to, for example, HDMI (R). | 10-07-2010 |
