OS81110AFR-D1A-010203-VAO

Controllers Overview

The OS81110AFR-D1A-010203-VAO is an Intelligent Network Interface Controller (INIC) designed for MOST150 networks, providing a bandwidth of 150 Mbits/s. It operates within a temperature range of -40 °C to +105 °C and supports operating voltages of 1.8 V and 3.3 V. The device is housed in a 48-pin QFN lead-free package compliant with RoHS standards. It features LVDS interfaces for FOTs, four high-speed I2S/SPDIF streaming ports, two serial Transport Stream Interfaces, and SPI connectivity.

Controllers Feature Summary

• Supports legacy control, synchronous, and packet channels alongside new Ethernet and isochronous transport mechanisms
• Enables seamless migration from MOST25/MOST50 using familiar INIC API and existing optical wire harnesses
• Provides direct connectivity for audio and video sources via dedicated streaming interfaces without glue logic
• Features flexible dynamic bandwidth management and low predictable node-to-node delay

Controllers Applications

• Automotive infotainment systems requiring high-quality audio and video streaming
• Multi-room sound systems and home theater setups utilizing active speakers
• Networked video distribution involving HD and SD source and sink devices
• Ethernet tunneling applications for internet access within vehicle networks

Controllers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package type and temperature rating. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Check for any errata or design defects listed in the datasheet before finalizing procurement plans.

Controllers Selection Notes

Select this controller when migrating existing MOST25 or MOST50 applications to MOST150 infrastructure. It is suitable for designs requiring direct connection to video SoCs and multi-channel audio amplifiers. Ensure the system architecture can accommodate the 48-pin QFN package and the specified voltage levels.

Controllers Part Context

This component belongs to the OS81110 series of Intelligent Network Interface Controllers developed by SMSC, now part of Microchip Technology. It represents the evolution of the INIC architecture specifically tailored for the higher bandwidth demands of MOST150 networks while maintaining backward compatibility with previous generations.

Controllers Replacement Considerations

The OS81110 is compatible with INIC25 and INIC50 architectures, allowing for application software migration with minimal changes. No direct single-part replacements are documented; consider evaluating other INIC family members if pinout or interface requirements differ.
