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
■ 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
■ HDMI ports at 1.65 Gb/s and up to 3.2 Gb/s
■ IEEE 1394a, b, or c up to 3.2 Gb/s
■ USB 2.0 ports up to 480 Mb/s (Hi-Speed)
■ Ethernet port: 10/100/1000 Mb/s
■ Video line protection
