OS85650 chip can replace FPGA solutions

SMSC has introduced the OS85650 I/O companion chip for MOST Intelligent Network Interface Controllers (INICs).

The OS85650 features multiple interfaces, powerful routing engine and the DTCP co-processor, allowing it to be used for various audio and video applications such as head units, rear-seat entertainment, amplifiers, television tuners and video displays.

The OS85650 works together with SMSC INICs for all MOST speed grades (MOST25, MOST50 and MOST150) and can replace many FPGA solutions.

The primary function of the OS85650 is to route data streams simultaneously between industry-standard application I/O interfaces, including MediaLB (three and six-pin), HBI, TSI, SPI and IS.

It 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 more than 300Mbit/s.

It is also possible to use the OS85650 as a bridge between MediaLB six-pin and MediaLB three-pin devices.

The high-performance routing engine operates at an internal speed up to 1.5GBit/s.

It can 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 eight multiple synchronous and isochronous data channels routed through the device.

It includes full AKE functionality and supports 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 such as DVD, Blu-ray Disc and HD-broadcasting services.

In addition to the OS85652, a pin-compatible version without a DTCP coprocessor is available.

Samples of the OS85650 and the OS85652 are available now.
