HDMIULC6-2M6

Ultra large bandwidth ESD protection

STMicroelectronics 

HDMIULC6-2x6

Ultra large bandwidth ESD protection

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

HDMIULC6-2M6

SOT-666

HDMIULC6-2P6

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

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.
