Semtech Corp. announces the RClamp®0524P and RClamp®0522P, two 5 V protection devices that are the first solid-state devices to reach 0.3pF in capacitance to meet the needs of High Definition Multimedia Interface (HDMI) 1.3 and other high-speed data lines. Recently, the HDMI 1.3 standard was introduced for improved color depth and audio output. HDMI 1.3 doubles the data rate of HDMI signals to 3.4 Gb/s per differential pair. Protecting the data lines at those speeds is a challenge because introducing any significant capacitance on the line will degrade signal integrity. The four-line RClamp0524P and two-line RClamp0522P are TVS arrays with a capacitance of 0.3pF between I/O pins, allowing either to be used on circuits operating at speeds greater than 3 GHz without signal attenuation. The ultra low capacitance means that common-mode chokes are not required for impedance compensation in HDMI designs.
