KIT_A2G_AUDIO_SHIELD

The AURIX^TM Audio Shield Board is a flexible extension shield to evaluate different audio applications in conjunction with the AURIX^TM TC375 lite kit.

Several functionalities can be explored such as

• Interfacing I²S / Left-Justified / TDM buses in Master-Mode
• Interfacing of PDM microphones in Stereo configuration and PDM decimation in software
• Synchronous interfacing of multiple PDM microphones in array configurations with PDM decimation in hardware
• Exploring different audio-clocking options including network-clock recovery for AVB applications
• Multipurpose Audio-Streaming over Ethernet
• Performance evaluation of XENSIV™ IM67D120A microphones and MERUS™ MA12070P amplifier
• Interfacing of A²B networks as A²B master-node
