Device Overview

Summary

Description

The OS85623 device belongs to Microchip’s family of I/O Companions (IOCs) and is specifically designed for use in video applications.

For ultra-low latency applications, such as camera modules for driver assistance systems, the OS85623 video companion device supports special H.264 encoding/decoding of I-Frames only.

For applications requiring higher compression, the OS85623 device also provides a DDR2 SDRAM Interface to which external memory can be made available for supporting I/P-Frame encoding/decoding.

Using an OS85623 device, audio and video data can be routed on/off a network via a MediaLB Port connected to one of Microchip’s Intelligent Network Interface Controllers (INICs). The audio and video exchange at the hardware ports may be either synchronous or asynchronous to the network frame rate.

Applications

  • H.264 Video Encoder/Decoder H.264 encoder/decoder supporting:
    • Ultra-low latency mode using I-Frames
    • Low latency and higher compression mode using I/P-Frames
  • Companion to Microchip’s INIC25, INIC50 and INIC150

If DTCP is required, please consider OS85621.
