Description
The D2 Audio DSP D2-1 Family (D2-81412, D2-81431, D2-81433, and D2-81435) is a fully self-contained 4-channel digital amplifier controller System-On-Chip (SOC). The D2-1 Family enables rapid system design for manufacturers of home theater receivers, multi-room distributed audio systems, and powered speakers. The D2-1 Family 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, as well as crossover and power limiting for powered speaker applications. The D2-1 Family includes 4-channels I2S/left-justified inputs (16-bit to 24-bit, 32kHz to 192kHz) and an optional S/PDIF receiver (16-bit to 24-bit). Boot options include: Self-boot from an external serial ROM, asynchronous SCI slave boot, and serial slave boot from a host microcontroller.
