Application note
HSP061-2 / HSP062-2 high speed line protection on HDMI 1.4 link
Introduction
This application note presents the HSP061-2 and HSP062-2 series and their capability to
protect HDMI 1.3 and HDMI 1.4 TMDS lines.
The HDMI interface is used for transmitting digital television audiovisual signals from DVD
players, set-top- boxes and other sources to television sets and other video displays.
The HSP series have been developed to be compliant with:
■ HDMI version 1.4 standard knowing the key point is the capability to transfer data with a
maximum rate of 3.4 Gbps per channel without distortion. This leads the HSP061-2 and
HSP062-2 to have a large bandwidth, to pass fast voltage slopes and to contain the 100
line impedance, HSP061-2 and HSP062-2 are used on the TMDS line.
■ IEC 61000-4-2 level 4 (8 kV contact discharge)
HSP061-2 and HSP062-2 series are composed of several packages and topologies (see
Chapter 1) to better fit customer requirements in terms of PCB design.
HSP061-2 has the ground pin in the middle of the package and is proposed in:
■ SOT-666: HSP061-2P6
■ µQFN-6L: HSP061-2M6
■ µQFN-4L: HSP061-2N4
HSP062-2 has the ground pin on the side of the package and is proposed in:
■ SOT-666: HSP062-2P6
■ µQFN-6L: HSP062-2M6
All these devices are flow-through.

1 HSP061-2 and HSP062-2 topology
HSP061-2 series protects two high speed lines (see Figure 1). This is a flow-through
package to get an easy layout and to ensure the 100 differential impedance on HDMI
(Figure 2). As PCB tracks are not cut, this offers the possibility to test a board with or without
protection depending on circuit portion to test.
The device is rated V
BR
min = 6 V @ 1 mA with a low typical leakage current of
0.1 nA @ 25 °C.
For further information refer to the product datasheet for HSP061-2.
HSP062-2 series uses the same technology as the HSP061-2.The only difference is
location the ground pin as shown in Figure 3 and Figure 4.
For further information refer to the product datasheet for HSP062-2.
