Microchip Technology has launched the first hardware-based audio endpoint solution for AVB – the LAN9360, a single chip Ethernet controller with embedded protocols.

The device is intended for connected vehicles that are increasingly relying on Ethernet for network connectivity and for developers looking to streamline infotainment system development and to more quickly adapt to manufacturers' evolving requirements.

The LAN9360 audio endpoint controller interconnects vehicles' infotainment devices including speakers, amplifiers, microphones, navigation systems, radio tuners and smart headrests with Ethernet AVB.

The device bridges audio between Ethernet AVB and Inter-IC Sound (I2S), Time Division Multiplexing (TDM) and Pulse Density Modulation (PDM) local audio interfaces and completely supports audio transmission over Ethernet AVB, including generalised Precision Time Protocol gPTP, timestamping, transport protocols and content protection with High-bandwidth Digital Content Protection (HDCP).
