The OS85650/2 I/O Companion ICs are High-Performance MediaLB®-I/O-Port Expanders 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 OS85652 is the pin-compatible version without a DTCP co-processor.

The I/O-Companion works together with SMSC INICs for all MOST speed grades (MOST25, MOST50 and MOST150) and can replace many of today’s expensive FPGA solutions.

The primary function of the OS85650/2 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.
