ESD solution for HDMI and DisplayPort

29 October 2008 Circuit & System Protection

New from Texas Instruments is a robust electrostatic discharge (ESD) solution that provides system-level ESD protection for eight high-speed differential lines, designed specifically for high-definition multimedia interface (HDMI) and DisplayPort connectors.

The TPD8S009’s flow-through, single-inline pin mapping optimises the board layout and lowers susceptibility to unwanted electromagnetic interference. Additionally, its architecture allows designers to easily add or remove the device without redesigning the system.

The device has differential capacitance of less than 0,05 pF to enable minimal differential signal distortion. The 0,8 pF line capacitance for each data line allows the device to achieve the high data rates suitable for high-speed video applications by supporting HDMI 1.3 and DisplayPort data rates up to 2,7 Gbps. It is compact for space-conscious equipment and comes in a small 6,5 x 2,5 mm SON-15 package.

The TPD8S009 is compliant to IEC 61000-4-2 (level 4) and operates over the industrial temperature range from -40°C to 85°C. It features 2,5 A peak pulse current (8/20 μs pulse) and is matched for 0,5 mm pitch DisplayPort and HDMI connectors for seamless routing and minimal line glitch due to ESD clamps.
