Self recovery fuse to protect the HDMI 1.3 interface program: HDMI1.3 interface standard to the previous HDMI data transmission speed doubled, each pair of differential signal line data transmission speed reached 3.4Gbps. Because of the high data transmission speed, the quality of the signal transmission, the excellent design of the circuit board is very important. In 3.4Gbps, the impedance (TDR), crosstalk and remote data eye, code for design of high speed interface HDMI1.3 has its own requirements. "In the HDMI design, the quality of the signal and crosstalk performance is the best, is very complex, and increased ESD, over current detection and protection circuit increases the difficulty of the design." To this end we designed the overtemperature and overcurrent protection device and self recovery fuse protection device with bidirectional voltage TVS tube, synergistic protection circuit, the HDMI1.3 interface is accomplished by means of testing, electrostatic discharge test in air is + 15kV + 8Kv, contact the test requirements, it is more than HDMI1.3 standards, can help the electronic equipment the manufacturer to speed up the product into the market.
The response rate for the TVS PS tube bidirectional protection device placed in the back of the HDMI connector, can help engineers to achieve the IEC61000-4-2 standard on the ESD protection. The signal source using HDMI, such as DVD players, set-top boxes, computer and other high definition signal source, standard power supply voltage transmitter interface must have overcurrent protection, high current to prevent short circuit or not normal for the signal generation equipment caused damage. 1812/1210/1206 series of self recovery fuse used in +5V power supply over current protection for users to choose, it uses a popular self recovery fuse SMD circuit protection devices.
The program can also be used for a variety of end products, including DisplayPort, USBPort, WiMAX and mobile phone base stations, Esata, as well as other high-speed data and analog interface.
