Product Brief
SII9222
Mobile High-Definition Link (MHLTM) Technology Transmitter
Low pin-count, HD video solution for mobile phones, digital still cameras, portable media players & camcorders
The SII9222 is an ultra low-power Mobile High-Definition Link (MHLTM) technology transmitter designed for power-sensitive consumer electronics devices such as mobile phones, digital cameras, portable media players, HD camcorders and other portable devices. Together with the companion MHL HDMI bridge, the SII9222 delivers low-cost, low-pin count, HDMI-interoperable HDTV connectivity for mobile electronics. The SII9222 transmitter is the world's first lowpin-count digital media transmitter featuring single data lane Transition Minimized Differential Signaling (TMDS), which reduces pin-count for small devices. The SII9222 transmitter delivers full high-definition video and digital audio through three pins on most mobile connectors. The MHL chipset, consisting of an MHL transmitter plus the SiI9290 MHL bridge chip, provides a High-Bandwidth Digital Content Protection (HDCP) engine and keys to securely distribute content between HDMI-enabled devices. Utilizing only two differential TMDS pairs for audio/video packets and a single-wire control bus, MHL technology delivers the necessary video bandwidth and replicates all the required control signals that comes with the traditional 19-pin HDMI interface. A low-cost companion MHL bridge chip converts the MHL signaling to HDMI compliant signals for connectivity to HDMI enabled DTVs.
SII9222 Typical Application
Applications
* Mobile Phones * Digital Still Cameras * Portable Media Players * HD Camcorders
Key Features
* Provides HD video with only three pins * RGB MPEG decoder interface * Ultra low active and standby power * Integrated HDCP engine and key for maximum security
In order to fit into the tight constraints of today's highly integrated mobile electronics, the SII9222 transmitter is housed in a tiny 5mm x 5mm, 64-ball chip scale BGA package. Even in this diminutive package, the MHL transmitters do not scrimp on performance, supporting resolutions from standard definition 480i/p all the way to high-definition 720p and 1080i. Silicon Image's MHL technology products are designed according to the requirements of the market segments. Together with its MHL-toHDMI bridge, SII9222 is compliant with the latest version of the industry leading HDMI standard for those market segments. The SII9222 carries audio/ video packets and control signals that are fully interoperable with the HDMI interface. In addition, all Silicon Image hardware and software solutions are developed and verified according to the latest HDMI Compliant Test Specification and Simplay HDTM HDCP interoperability compliance requirements.
