AD2428BCPZ

AD2428B is a A2B main/subordinate 4xPDM XCVR w I2S/TDM. The Automotive Audio Bus (A2B®) provides a multichannel, I2S/TDM link over distances of up to 15m between nodes. It embeds bidirectional synchronous pulse-code modulation (PCM) data (for example, digital audio), clock, and synchronization signals onto a single differential wire pair. A2B supports a direct point to point connection and allows multiple, daisy chained nodes at different locations to contribute and/or consume time division multiplexed (TDM) channel content.

• Line topology and up to 15m between nodes, up to 40m overall cable length
• Communication over distance such as synchronous data, multichannel I2S/TDM to I2S/TDM
• Control and status information I2C to I2C, GPIO and interrupt
• Configurable with SigmaStudio graphical software tool
• 8bit to 32-bit multichannel I2S/TDM interface programmable I2S/TDM data rate
• Simultaneous reception of I2S data with up to 4 PDM microphones
• Unique ID register for each transceiver and crossover or straight-through cabling
• Programmable settings to optimize EMC performance
• 32 lead LFCSP package
• Operating temperature range from -40°C to 105°C
