GENEVA, SWITZERLAND: 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.
