Ultra-large-bandwidth ESD protection for HDMI connections

21 March 2007 Circuit & System Protection

STMicroelectronics has enlarged its portfolio of ultra-low-capacitance protection ICs for the high-definition video market. The new device allows a high definition multimedia interface (HDMI), to operate at full HDMI speed of 1,65 Gbps and even up to 3,2 Gbps, with full 15 kV contact and air ESD protection.

Offering one of the best bandwidths available (greater than 5 GHz), the new HDMIULC6-4SC6 is a monolithic, application-specific device that provides rail-to-rail protection of four data lines without compromising signal integrity.

Protecting high-speed data ports is particularly challenging. Any capacitive loading introduced by protection devices can significantly degrade the signal integrity. This is particularly significant at the high data rates required by HDMI connections in computer and consumer electronics. Previous solutions on the market typically presented a capacitive loading of several pF, which is high enough to require designers to make difficult trade-offs between the level of protection and the resulting signal degradation at typical working data rates.

The device's ultra-low line capacitance (0,6 pF) provides a new level of performance. The ultra-high cut-off frequency of 5,3 GHz guarantees data integrity. The HDMIULC6-4SC6 has good impedance matching (0,015 pF), low leakage current (0,5 μA max), and minimal channel imbalance, signal skew and crosstalk (0,007 pF).

The new device is compatible with other high-speed interfaces such as IEEE 1394a/b, USB2.0, Ethernet links, and video lines. The footprint of the HDMIULC6-4SC6 (SOT23-6L package) is compatible with ST's popular USBLC6-4SC6 and DVIULC6-4SC6 ESD protection devices for USB 2.0 and DVI ports respectively, allowing easy board upgrades.
