STMicroelectronics Sets the Standard for Protecting High-Speed Multimedia Interfaces
STMicroelectronics has raised the performance of ESD protection for equipment such as DisplayPort monitors and PCs by introducing a Transient Voltage Suppressor (TVS) allowing increased high-definition (HD) picture quality, thanks to its best-in-class low capacitance. By 2013, approximately 100 million portable PCs will ship with a DisplayPort output for connection to an external high-definition screen1.The
ST, with its latest ESDAXLC6-1MY2 Transient Voltage Suppressor (TVS), has set a new benchmark ultra-low capacitance for this type of device, thereby preserving picture quality while maintaining ESD protection meeting applicable industry standards. This eXtremely Low Capacitance (XLC) device places a loading of 0.35pF maximum on the signal line. This low capacitance provides a signal bandwidth of 6-7GHz, which allows the 2.7Gbit/s data streams of a DisplayPort interface to pass through without distortion. ST’s new TVS will also protect HDMI, USB3.0 and eSATA interfaces, which have similar per-channel data rates.
By using the same footprint and pin arrangement as older devices of higher capacitance, ST’s new TVS provides a direct upgrade or second-source for any existing product, and will be a popular choice for new designs. It occupies just 0.6mm2 of printed-circuit-board space, and only a single device is required per signal line. The protection provided meets IEC 61000-4-2, allowing equipment to withstand an ESD event up to ±8kV in direct contact with the signal conductor.
Features of the ESDAXLC6-1MY2:
* Single-channel device protecting one high-speed line
* 0.35pF maximum capacitance between signal line and ground
* Greater than 6GHz signal bandwidth
* Certified to IEC 61000-4-2 level 4
* Industry-standard SOD882 miniature footprint (1mm x 0.6mm)
The ESDAXLC6-1MY2 is available immediately in production volumes, priced at $0.15 in quantities of 12,000. Alternative pricing options are available for larger order quantities.
