LAN9360A-I/CQBT-100

Controllers Overview

The LAN9360A-I/CQBT-100 is an Audio Video Bridging (AVB) audio endpoint network controller manufactured by Microchip Technology. It integrates support for gPTP, AVTP, and RTP protocols to facilitate synchronized multimedia transmission over Ethernet networks. The device operates within a temperature range of -40°C to +85°C and is housed in a QFN package with the suffix indicating reel packaging. This component is designed for high-performance audio applications requiring precise timing synchronization and compliance with IEEE standards.

Controllers Feature Summary

• Integrates hardware support for IEEE 802.1AS gPTP and IEEE 1722 AVTP protocols
• Supports up to 40 audio channels for complex multi-channel audio routing
• Includes security features such as HDCP, secure boot, and secure firmware update capabilities

Controllers Applications

• Professional audio networking equipment requiring AVB compliance
• Automotive infotainment systems utilizing Time-Sensitive Networking
• Industrial control systems needing deterministic audio data transmission

Controllers Procurement Notes

Verify current availability status as the manufacturer has issued a product discontinuance notification dated February 8, 2024. Confirm that the specific ordering suffix matches the required package type and temperature grade. Ensure compatibility with existing system designs before procurement due to end-of-life status.

Controllers Selection Notes

Select this component when designing systems requiring integrated AVB protocol handling without external processors. Consider the thermal performance of the QFN package for enclosed environments. Evaluate the need for the specific security features provided, such as secure boot, against alternative general-purpose controllers.

Controllers Part Context

This part belongs to the LAN9360 series of intelligent Ethernet controllers focused on Audio Video Bridging. It is distinct from standard Ethernet switches by its emphasis on real-time audio streaming and synchronization. The 'I' indicates industrial temperature rating, while 'CQBT' specifies the package and tape/reel configuration.

Controllers Replacement Considerations

Due to the End-of-Life status announced in early 2024, direct replacements may be limited. Designers should evaluate newer Microchip AVB solutions or generic Ethernet controllers with software-based AVB stacks. Verify pinout and register compatibility if migrating to similar legacy parts.
