RENESAS D2-81431-LR

The D2Audio™ D2-814xx is a fully self-contained 4-channel digital amplifier controller System-On-Chip (SOC). The D2-814xx enables rapid system design for manufacturers of home theater receivers, multi-room distributed audio systems, and powered speakers. The D2-814xx contains a high-performance digital switching controller to play any input source on any output channel. A configurable audio signal processor provides equalization, volume control, tone control, and compression for each channel, also crossover and power limiting for powered speaker applications. The D2-814xx includes 4-channels I2S/Left-Justified inputs (16-bit to 24-bit, 32kHz to 192kHz), optional S/PDIF receiver (16-bit to 24-bit). Boot options include: Self-boot from external serial ROM, asynchronous SCI slave boot, and serial slave boot from host uCon.
