Microchip Technology has announced the first hardware-based audio endpoint for AVB, the LAN9360, a single chip Ethernet controller with embedded protocols.
The LAN9360 audio endpoint controller interconnects vehicles’ infotainment devices including speakers, amplifiers, microphones, navigation systems, radio tuners and smart headrests with Ethernet AVB. The LAN9360 bridges audio between Ethernet AVB and Inter-IC Sound (I2S™), Time Division Multiplexing (TDM) and Pulse Density Modulation (PDM) local audio interfaces. It completely supports audio transmission over Ethernet AVB, including generalized Precision Time Protocol gPTP, timestamping, transport protocols and content protection with High-bandwidth Digital Content Protection (HDCP). It also supports secure boot and secure remote updates over Ethernet. Unlike other Ethernet bridging networking products requiring System-on-Chip (SoC) microcontrollers (MCUs) plus third-party software stacks, the LAN9360 endpoint device requires no software integration, enabling designers to configure the device simply and quickly to manufacturers’ unique audio and networking requirements.
The device is validated to the IEEE® 802.1BA-2011, IEEE 802.1AS, IEEE1722 and IEEE1733 specifications for Ethernet networks and is certified to the standards for AVB interoperability and reliability established by the Avnu Alliance consortium.
"In looking for an AVB solution for our Automotive Remote Tuners products, the LAN9360 allowed us to develop on a trusted platform quickly, without changing our current software," said Pierrick Labeau, Research & Development Manager, FIAMM Horn & Antennas - Elettra 1938 Group.
