SMSC - Low-Cost, High-Performance I/O Port Expander and DTCP Co-Processor for MOST Networks
SMSC has announced the OS85650 I/O companion chip for MOST® Intelligent Network Interface Controllers (INICs). With its multiple interfaces, powerful routing engine and the DTCP co-processor, the OS85650 can be used for various audio and video applications such as Head Units, Rear Seat Entertainment, Amplifiers, TV-Tuners and Video Displays. The OS85650 works together with SMSC INICs for all MOST speed grades (MOST25, MOST50 and MOST150) and can replace many of today's expensive FPGA solutions.
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 I²S. It is the first MediaLB 6-Pin device that supports all features of the MOST150 multimedia network. 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 high-performance routing engine operates at an internal speed up to 1.5 GBit/s. It is able to route on top of the standard MOST network communication, Ethernet IP packets, multiple MPEG-TS and several high quality 7.1 audio streams. 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 full 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 high quality audio and video content, like DVD, Blu-ray Disc and HD-Broadcasting Services.
