描述 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.

特性 Features

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

■ Ultra low capacitance: 0.6 pF @ 825 MHz

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

■ Very low leakage current: 0.5 μA max.

■ Fast response time compared with varistors

■ Protects VBUS when applicable

■ RoHS compliant

Benefits

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

■ ESD protection of VBUS when applicable.

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

■ Large bandwidth to minimize impact on data signal quality

■ Consistent D+ / D- signal balance:

– Ultra low impact on intra- and inter-pair skew

– Matching high bit rate HDMI requirements and ready for future evolution

■ Low PCB space occupation - 1.45 mm2 for μQFN

■ Low leakage current for longer operation of battery powered devices

■ Higher reliability offered by monolithic integration

■ 500 μm pitch for μQFN 6 leads

Complies with these standards

■ IEC 61000-4-2 level 4

– 15 kV air discharge

– 8 kV contact discharge

■ MIL STD883G-Method 3015-7

Applications
