[July 03, 2009] SMSC Releases I/O Port Expander and DTCP Co-Processor Tweet Jul 03, 2009 (Close-Up Media via COMTEX) -- SMSC, a semiconductor company that provides Smart Mixed-Signal Connectivity solutions, announced the introduction of its OS85650 I/O companion chip for MOST Intelligent Network Interface Controllers (INICs). With its multiple interfaces, routing engine and the DTCP co-processor, the company noted, the OS85650 can be used for various audio and video applications such as Head Units, Rear Seat Entertainment, Amplifiers, TV-Tuners and Video Displays. "With its expanded communication ports, this companion chip allows the INIC family to stay cost optimized in providing minimal application interfaces at a low pin count," said Stefan Lux, Product Marketing Manager for SMSC's Automotive group. "Together with the INIC, the OS85650 offers a complete solution for network applications, including data exchange on MOST networks." The primary function of the OS85650 is to route data streams simultaneously between industry standard application I/O interfaces, including MediaLB (3-Pin and 6-Pin), HBI, TSI, SPI and I?S. Together with the 16 bit parallel Host Bus Interface (HBI), it enables a high-speed connection between the INIC150 and multiple External Host Controllers (EHCs) with over 300Mbit/s. It is also possible to use the OS85650 as a bridge between MediaLB 6-Pin and MediaLB 3-Pin devices. The Digital Transmission Content Protection (DTCP) co-processor autonomously encrypts and decrypts up to 8 multiple synchronous and isochronous data channels routed through the device. It includes AKE functionality and supports both M6 and AES-128 cipher engines according to DTCP for MOST and DTCP-IP. This content protection is required for audio and video content, like DVD, Blu-ray Disc and HD-Broadcasting Services. In addition to the OS85652, a pin-compatible version without a DTCP coprocessor is available immediately. ((Comments on this story may be sent to [email protected])) [ Back To TMCnet.com's Homepage ]
