STMicroelectronics has introduced a chip that simplifies the design of HDMI-compatible connectors. Targeted at high-definition products such as set-top boxes, Blu-ray players, game consoles and HDTVs, the new HDMI2C1-5DIJ ensures that designers can meet the requirements of the HDMI standard version 1.3. It also provides ESD protection, signal enhancement, and HDMI control signal level shifting, which reduces board space by up to 70% compared to an equivalent network of discrete devices.

Although there are protection ICs that provide ESD protection, level shifting, and two control channels for HDMI high-speed audio and video signal lines, these products eliminate the designer's choice of the best audio and video with the largest bandwidth and the smallest capacitive load. The opportunity to protect the IC. These features are especially important when protecting HDMI audio and video signal lines, as the integrity of the signal is reduced, which can result in poor end-user experience.
HDMI2C1-5DIJ provides ESD protection required by the HDMI standard, and the 8kV contact discharge voltage complies with IEC 61000-4-2 Level 4 international standards. With a high equivalent capacitance, signal enhancement ensures signal reliability over long and/or low-cost cables. A built-in level shifting circuit allows low voltage control signals to be applied directly to the 5V HDMI signal circuit without the need for additional components. The HDMI2C1-5DIJ also prevents potential devices that input signals to the HDMI circuit from posing a potential hazard to the circuit.
The HDMI2C1-5DIJ is a companion chip to the STMicroelectronics HDMIULC6-4SC6 and is used to protect HDMI audio and video signal lines. The line capacitance of the new product is ultra-low, only 0.6pF, and the bandwidth exceeds 5GHz, enabling designers to maximize HDMI-compatible ESD protection while maximizing signal integrity. The combination of these two chips allows designers to implement HDMI-compliant interface designs on high-definition devices based on ST's STi5xxx or STi7xxx HD decoder ICs.
The HDMI2C1-5DIJ is available in a 16-pin QFN 5 x 4 package.
