Description
The D2-6 family (D2-71083, D2-74083, D2-71583, D2-74583, and D2-74383) digital audio processor devices are complete System-on Chip (SoC) audio processor and Class-D amplifier controllers. Integrated DSP processing and configurable audio processing algorithms provide an extremely flexible platform for feature rich and cost-effective quality audio solutions which benefit from the addition of Class-D amplifiers and DSP audio processing, meeting demands of consumer electronics applications. The 12 integrated digital PWM controllers can be used in a variety of multi-channel audio system configurations, supporting powered as well as line outputs. Fully protected amplifier control provides efficient and clean Class-D power output support. The D2-6 device family supports full audio decoding for formats including Dolby® Digital, Dolby® Pro Logic IIx, AAC LC™, DTS® Digital Surround, and Dolby® Digital Plus. The D2-6 family is pin-compatible and function/feature compatible with the D2-3 family devices, enabling additional decoding capability to existing designs, or providing cost optimization to lower-featured systems not requiring the additional audio processing and decode capability.

- Application NotePDF 184 KB r32an0007eu0100-d2-audio-dsp-output-filter-design May 20, 2019AI-generated Summary: The document explains the design and selection of output filters for D2 Audio DSP half-bridge and full-bridge configurations. It details the half-bridge output stage, filter network, and bias network that provides a DC offset and AC ground reference. It covers filter operation principles, emphasizing the second-order LC low-pass filter to attenuate high-frequency PWM signals. Loudspeaker impedance impacts filter damping and response. Recommended component values for inductors, capacitors, and bias networks are provided for various load impedances and power ratings.
- Application NotePDF 147 KB r32an0006eu-d2-audio-eeprom-spi May 15, 2019AI-generated Summary: The document explains procedures for writing firmware and parameter data to EEPROM or SPI Flash memories in D2 Audio DSP systems using an external microcontroller. It details booting methods, control pin configurations, and communication protocols for different D2 Audio device families (D2-1, D2-3, D2-4, D2-6). The process involves loading bootloader or boot code hex files, writing settings to memory, and rebooting to run from the updated non-volatile memory. Specific I2C addresses and pin states are critical for successful operations.
- Application NotePDF 155 KB r32an0005eu-d2-3-d2-6-audio-soc May 15, 2019AI-generated Summary: The document details the programmable I/O pin assignments and hardware functions for the D2 Audio SOC family. It explains the allocation of dedicated and assignable pins for features like master volume control, headphone detection, mute function, temperature monitoring, power stage protection, and error reporting. Each function's enable/disable options, pin assignments, and operational parameters are configurable via the D2 Audio Customization GUI. The guide emphasizes efficient pin usage and protection mechanisms for audio output stages.
- Application NotePDF 297 KB r32an0002eu-d2-audio-dsp May 13, 2019AI-generated Summary: The D2 Audio Customization GUI v3 offers a comprehensive set of audio processing blocks including Excursion Control, Delay, Compressor, Expander, Envelope VCA, Reverb, Chime Generator, RMS Level Meter, Fade-Pan, Mono Mixer, Dither Generator, Harmonics Generator, and Compound Blocks. It supports real-time interactive control with graphical displays for magnitude and phase, enabling precise parameter adjustments. The software allows flexible signal flow editing with dynamic register addressing and integration of third-party virtualization algorithms. Each audio block has dedicated registers, and the system generates updated header files for seamless controller integration.
