Datasheet

STMicroelectronics has unveiled an IC for use with today’s highest-speed multimedia and storage interconnects, including HDMI, DisplayPort, USB 3.0, Serial ATA (SATA) and DVI. The new device provides ESD protection for four data lines within a 1x2mm-outline package, saving at least 30% of PCB space compared to other devices.

As these high-speed interconnect standards maximize ease of use – specifying convenient, miniaturized connectors and cables – consumers can easily connect and disconnect devices such as high-definition video equipment, terabyte storage, multi-megapixel cameras, and personal media devices including smartphones. This increases the risk of damage to internal circuitry by electrostatic discharges (ESD), which can occur when a device is touched or when a cable is connected or removed.

By providing a convenient one-chip ESD-protection solution, ST’s HSP061-4NY8 addresses a large and important market: total worldwide shipments of equipment containing an HDMI or DisplayPort connection, for example, are expected to exceed one billion units by 2012, according to industry analysts.

The HSP061-4NY8 provides the industry with a single orderable part capable of protecting circuits using any of these multi-gigabit standards, enabling economies of scale as well as significant advantages in efficiency throughout product design, purchasing, and assembly.

The device contains a network of Transient Voltage Suppression (TVS) diodes capable of protecting two pairs of high-speed differential data lines. These diodes are sufficient to provide complete protection for the 5.0 Gbit/s SuperSpeed bus defined in the new USB 3.0 specification. A single HSP061-4NY8 can also protect all the data lines of an HDMI port, an entire channel in SATA interfaces, up to and including the latest 6Gbit/s SATA 3.0 standard, or a two-lane DisplayPort interface.

Technical features of the HSP061-4NY8:

* ESD protection complying with: IEC61000-4-2 level 4 (8kV air discharge) and MIL-STD 883G Method 3015-7 Class 3B (>8kV)
* Ultra low capacitance: 0.6pF
* 5.8GHz bandwidth and 100 Ohm differential impedance: suitable for 3.4Gbit/s data lines
* Low leakage current: 100nA at 25°C
* 0.55mm-high 1x2mm 8-lead microDFN package
