LAN9360 from Microchip is the recently released fully integrated AVB audio endpoint solution that helps in reducing development time and eliminates the need for stack integration and additional software and firmware development. This single-chip Ethernet controller with embedded protocols interconnects the infotainment devices of the vehicle such as speakers, amplifiers, microphones, navigation systems, radio tuners, and smart headrests with Ethernet AVB.
The LAN9360 audio endpoint controller bridges audio between Ethernet AVB and Inter-IC Sound (I2S), Time Division Multiplexing (TDM), and Pulse Density Modulation (PDM) local audio interfaces. It 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).
Additionally, the device also supports secure boot and secure remote updates over Ethernet. Unlike other Ethernet bridging networking solutions, the LAN9360 endpoint device requires no software integration System-on-Chip (SoC) microcontrollers (MCUs) and third-party software stacks thereby enabling designers to configure the device simply and speedily while meeting manufacturers’ unique audio and networking requirements.
