ST delivers industry’s first integrated ESD protection IC for DisplayPort

INDIA: STMicroelectronics has announced a new chip delivering enhanced protection for PCs, monitors, projectors and similar equipment featuring the latest DisplayPort interface, the next-generation successor to traditional VGA and DVI connections.

ST’s DPIULC6-6DJL provides essential protection for the sensitive DisplayPort circuitry against electrostatic discharges (ESD) that could damage or destroy the display device.

ST has optimized the protection to meet the different needs of the main and auxiliary data channels defined in the DisplayPort Vesa 1.1a standard. Moreover, although the protection device is capable of blocking hazardous voltage spikes, it is effectively transparent to the high-speed data signals and allows them to pass virtually undistorted at the highest possible speed and power to ensure consistent high-quality multimedia experiences for users.

Main features of the DPIULC6-6DJL:
* 5GHz bandwidth.
* 100Ω ± 10 percent characteristic impedance (100% compatible with 100Ω differential layout).
* Capacitance defined according to Vesa 1.1a standard: less than 1.5pF.
* Low capacitance variation: 0.05pF.
* Pin-out optimized for easy PCB design.
* Meets applicable standards:
-- IEC 61000-4-2 level 4–15kV (air discharge); 8kV (contact discharge).
-- MIL STD 883G-Method 3015-7: class 3B 8kV HBM (Human Body Model).
-- VESA DisplayPort Standard Version 1.1a.

The DPIULC6-6DJL is available now in a 5 x 6mm leadless QFN package featuring 18 I/Os; pricing starts at $0.30 for orders over 3,000 units.
