HDMI and MHL IP for Mobile and Digital Home Connectivity
By Manmeet Walia, Sr. Product Marketing Manager, Synopsys
HDMI and MHL PHY & Controller IP solutions enable chip designers to build next-generation multimedia SoCs for a broad range of digital home and mobile multimedia platforms. In addition to lowering BOM cost with wide variety of advanced, value-added features, the solutions also simplify software and driver development efforts for seamless system integration and faster time-to-market.
With 18 Gbps bandwidth and performance/simplicity/reliability as its key advantages, HDMI is the standard multimedia interface for digital home devices and continues to rapidly grow its install base. In fact, HDMI has continued to accelerate its reach beyond the digital home and into an increasingly broad array of applications such as digital office, industrial and more. HDMI's global acceptance as the connectivity technology of choice is largely due to its ability to deliver the highest quality audio/video signal over a single cable. With the ratification of HDMI version 2.0, we see further adoption of HDMI in 4K digital televisions (DTVs) and other high end digital home devices.
The Mobile High-Definition Link (MHL) interface is optimized for mobile platforms and leverages HDMI technology. MHL requires five signal/connector pins versus the 19 signal/connector pins required by HDMI protocols and can map itself to existing popular connectors in the ecosystem (i.e., USB 2.0 in cell phones and HDMI in DTVs). With support for a maximum bandwidth of 6.0 Gbps and power delivery of up to 10 Watts, MHL offers an enhanced multimedia interface technology for mobile devices such as cell phones, phablets and tablets. MHL continues to prevail over competing wireless interface technologies by virtue of features like power delivery, high performance, low latency and security.
