Chip guards HDMI, DisplayPort connectors from ESD
Keywords:system-level ESD protection? high-definition multimedia interface? DisplayPort connectors?

Texas Instruments Inc. has introduced a robust ESD solution that provides system-level ESD protection for eight high-speed differential lines, designed specifically for HDMI and DisplayPort connectors.
The TPD8S009's flow-through, single-inline pin mapping optimizes the board layout and lowers susceptibility to unwanted electromagnetic interference. Additionally, this unique architecture allows designers to easily add or remove the device without redesigning the system. The ESD solution increases overall system reliability in devices such as notebook or desktop PCs, TVs or DVD players.
The TPD8S009 has the industry's lowest differential capacitance of less than 0.05pF, which enables minimal differential signal distortion. The 0.8pF line capacitance for each data line allows the device to achieve the higher data rates suitable for high-speed video applications by supporting HDMI 1.3 and DisplayPort data rates up to 2.7Gbit/s. It is compact for space-conscious equipment and comes in a small 6.5mm x 2.5mm SON-15 package.
Other key features include IEC 61000-4-2 (Level 4) system level ESD compliant, industrial temperature range (-40C to 85C), 2.5A peak pulse current (8/20us Pulse) and match with 0.5mm-pitch DisplayPort and HDMI connectors for seamless routing and minimal line glitch due to ESD clamps.
The TPD8S009 is optimized to work with TI's family of video switch buffers for DisplayPort and HDMI, such as the SN75DP129 DisplayPort to HDMI translator and the TMDS351 HDMI switch. Other ESD protection devices from TI support PC and consumer electronics applications. This ESD protection portfolio contributes to TI's broad interface product offering including families of products for USB, 1394, RS-232, UART, and PCIe standards.
The TPD8S009 is available now in a 15-pin SON package. Suggested resale pricing in 1,000-unit quantities is 61 cents. Free samples are available from TI's Website.
