Supporting up to 32 audio channels per node with less than 50 us end-to-end latency, it dramatically simplifies automotive audio wiring harnesses. The A2B bus can deliver phantom power to remote nodes, eliminating separate power cables for distributed microphones and speakers. The W suffix indicates automotive temperature range (-40 to +105 deg C). The AD2428 can operate as either a main node (bus controller) or subordinate node in a daisy-chain topology of up to 10 nodes over 40 meters total cable length.","working_principle":"The AD2428WCCSZ-RL implements the A2B protocol which uses a superframe structure transmitted over the twisted-pair bus at up to 50 Mbps. Each superframe contains downstream data (main to subordinates), upstream data (subordinates to main), and I2C control packets. The main node generates the bus clock and synchronizes all subordinate nodes. The physical layer uses a self-clocked encoding scheme that recovers clock and data from the received signal. Phantom power (up to 300 mA at 12V) is delivered over the bus cable using a DC bias on the differential pair, with DC blocking capacitors at each node. The I2C pass-through feature allows the main processor to configure remote I2C peripherals (codecs, amplifiers) through the A2B bus without additional wiring.","pin_description":"\n
