描述 Description

The HDMIULC6-4SC6 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 (5.3 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

■ 4 line 15 kV ESD protection

■ Protects VBUS when applicable

■ Ultra high bandwidth - no inluence 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

■ SOT23-6L package

■ RoHS compliant

Benefits

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

■ ESD protection of VBUS when applicable.

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

■ Minimized rise and fall times for maximum data integrity

■ Consistent D+ / D- signal balance:

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

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

■ Low PCB space occupation - 9 mm2 maximum foot print

■ Low leakage current for longer operation of battery powered devices

■ Higher reliability offered by monolithic integration

Main 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
