Description

The HDMIULC6-2x6 is a monolithic, application specific discrete device dedicated to ESD protection of the HDMI connection. It also offers the same high level of protection for IEEE 1394a and IEEE 1394b/c, USB 2.0, Ethernet links, and video lines.

Its ultra high cutoff frequency (5.9 GHz) secures a high level of signal integrity. The device topology provides this integrity without compromising the complete protection of ICs against the most stringent ESD strikes.

Features

¡ö 2-line ESD protection (at 15 kV air and contact discharge, exceeds IEC 61000-4-2)

¡ö Ultra low capacitance: 0.6 pF @ 825 MHz

¡ö Ultra high bandwidth - no influence on signal rise and fall times - maximised number of signal harmonics

¡ö Very low leakage current: 0.5 ?A max.

¡ö Fast response time compared with varistors

¡ö Protects VBUS when applicable

¡ö RoHS compliant

Benefits

¡ö ESD standards compliance guaranteed at device level, thus greater immunity at system level

¡ö ESD protection of VBUS when applicable.

¡ö High efficiency due to low residual voltage when confronted by an ESD surge

¡ö Large bandwidth to minimize impact on data signal quality

¡ö Consistent D+ / D- signal balance:

¨C Ultra low impact on intra- and inter-pair skew

¨C Matching high bit rate HDMI requirements and ready for future evolution

¡ö Low PCB space occupation - 1.45 mm2 for ?QFN

¡ö Low leakage current for longer operation of battery powered devices

¡ö Higher reliability offered by monolithic integration

¡ö 500 ?m pitch for ?QFN 6 leads

Complies with these standards

¡ö IEC 61000-4-2 level 4

¨C 15 kV air discharge

¨C 8 kV contact discharge

¡ö MIL STD883G-Method 3015-7

Applications
