TI Introduces Flexible, Eight-Channel ESD Solution for HDMI and DisplayPort
(Technology News, 18 Aug 2008 )
Texas Instruments (TI) today introduced 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 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 computers, televisions or DVD players.
The TPD8S009 has the industry’s lowest differential capacitance of less than 0.05 pF which enables minimal differential signal distortion. The 0.8 pF 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 2.7 Gbps. It is compact for space-conscious equipment and comes in a small 6.5 mm x 2.5 mm SON-15 package.
Other key features include the following:
· IEC 61000-4-2 (Level 4) system level ESD compliant · Industrial temperature range: -40˚C to 85˚C · 2.5A peak pulse current (8/20μs Pulse) · Match with 0.5 mm-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 PCI-Express standards. Please see the Interface Selection Guide for more information. To learn more about the TPD8S009, watch the videocast at www.ti.com/esdvideo.
