Mobile High-Definition Link™ (MHL™) is on its way

New Silicon Image VastLane Products Are First to Implement Mobile High-Definition Link™ (MHL™)  

MHL Lets Mobile Phones, Digital Cameras and Portable Media Players Deliver High-Definition Content

LAS VEGAS, Jan. 7, 2008 – At the 2008 International CES, Silicon Image, Inc. (NASDAQ: SIMG), a leader in semiconductors for the secure storage, distribution and presentation of high-definition content, today announced three new VastLane™ products using the Mobile High-Definition Link™ (MHL™), which enables consumers to connect mobile phones, digital cameras, portable media players and other mobile devices directly to digital televisions so they can watch and listen to content on HDTVs with pristine digital quality. In support of Silicon Image’s mission of delivering digital content everywhere, the Silicon Image VastLane SiI9220 and SiI9222 are the first MHL transmitters for mobile devices and the VastLane SiI9290 is the first MHL bridge chip for the docking station or dongle.

These semiconductors are the first products that enable MHL, which Silicon Image unveiled today (see separate release, “SILICON IMAGE INTRODUCES NEW MOBILE HIGH-DEFINITION LINK”).

“Personal media on mobile devices is growing at an explosive rate. Being able to connect your personal media player or mobile phone to a digital television has become as important as the connecting a DVD player or set-top box to the TV,” said Dale Zimmerman, vice president of marketing for Silicon Image. “MHL enables this connection and we will provide MHL solutions for both mobile devices and HDTVs going forward.”

To equip a mobile phone or other device with MHL, the manufacturer would add an MHL transmitter chip to the mobile device. The manufacturer would also sell a docking station or dongle, containing a bridge chip that performs the conversion into a standard High-Definition Multimedia Interface™ (HDMI™) signal. The docking station or dongle will have a standard HDMI connector on the other end, allowing the docking station to be plugged directly into HDMI-enabled HDTVs. This two-chip solution offers HDMI functionality to small devices that until now could not consider HDMI due to the size of the connector and pin requirements.

The SiI9220 and SiI9222 transmitters are the world’s first low-pin-count digital media transmitters. Both chips feature a single data lane Transition Minimized Differential Signaling (TMDS) solution, which reduces pin count for small devices. These transmitters can deliver full high-definition (HD) video and digital audio through five pins on miniature connectors. The MHL chipset (a transmitter plus the SiI9290 MHL bridge chip) provides a High-Bandwidth Digital Content Protection (HDCP) engine and keys that enable the secure distribution of content between HDMI-enabled devices. The SiI9220 incorporates Mobile Industry Processor Interface (MIPI) input while the SiI9222 supports parallel RGB digital video inputs providing mobile OEMs with flexibility to use media processors with the emerging MIPI architecture or standard video bus architecture.

The dramatically low active and standby power consumption of the SiI9220 and SiI9222 transmitters extend battery life in mobile devices. In the active setting at 720p and 1080i, the transmitters consume no more than 60 milliwatts (mW), an industry low. On standby mode, the transmitters consume just 20 microwatts (µW).

To complete the connection, MHL technology also uses a bridge chip that performs the conversion into a standard HDMI signal. The SiI9290 MHL-to-HDMI bridge provides a cost-effective solution for a docking station or dongle that is fully HDMI compatible. Together, the SiI9290 and the SiI9220/9222 form a low cost chipset that allows MHL-enabled mobile devices to output HD video through a small connector and directly connect to any HDMI-enabled HDTVs. Consumers will be able to see and hear all their content on a large display, in pristine digital HD quality, with the simplicity of a single-cable HDMI connection.

“Our newest offering of mobile products will have a tremendous impact on the way we use our mobile devices to consume media,” said Stevan Eidson, director of product marketing for Silicon Image’s VastLane product line. “Implementing these products and MHL technology will allow us to enjoy digital content on large screens – when and where we want – in high definition. Silicon Image continues to lead the way in innovation and in delivering the most advanced mobile solutions in HD content.”
