Intersil has introduced the DAE-6 range of single-chip audio system solutions, which are designed to provide dramatically improved audio quality in consumer products.

The new devices enable a high-end audio experience in an easy-to-implement, single-chip solution.

The Intersil D2Audio DAE-6 range provides a complete System-on-Chip (SoC) solution, including an integrated audio processor and multi-channel Class-D amplifier controller.

By integrating a digital signal processor (DSP) with configurable audio-processing algorithms, the DAE-6 provides audio system designers with an extremely flexible and feature-rich platform.

This cost-effective solution meets the increasing demands of consumer electronics applications such as portable music players, PC multimedia speakers, automotive sound systems and home theatre systems, including surround bars and home-theatre-in-a-box systems (HTiBs).

The DAE-6 range features embedded mastering-level software, providing customers with precision audio tuning for any audio-enabled device.

Including D2Audio sample rate converters (SRCs) on each audio channel, the DAE-6 range supports a variety of multi-channel digital and analogue inputs, including up to eight channels of asynchronous digital serial input.

Multi-channel Class-D amplifier outputs can be configured for various power levels from 10W to more than 500W and include complete fault protection with automatic recovery, improving system performance without sacrificing power efficiency.

This new range of D2Audio products features discrete decoders for Dolby Digital, DTS Digital Entertainment and AAC-encoded audio streams, captured via integrated S/PDIF receivers and followed by up to 12 channels of audio processing.

This processing is configurable with multi-band parametric equalisation, assignable filtering, reverb, matrix decoding and bass management.

In addition, the DAE-6 range includes automatic algorithms for correcting room acoustic imperfections or performance anomalies in speaker drivers and enclosures.

Pin-compatible with the earlier DAE-3 series, the DAE-6 range gives product designers the flexibility to migrate an existing design without creating new printed circuit boards, or to create several performance options for tiered products using the same PCB and chassis.

Its integrated topology includes full support for all standard surround-sound decoders (including Dolby Digital and DTS), as well as fully configurable and routable signal paths.

Sample rates from 32 to 192kHz will accommodate any source, from low-resolution compressed music downloads to home theatre systems to higher-definition PCM outputs from Blu-ray players.

In addition to speaker-level outputs (supporting bridged, half-bridged or bridge-tied-load topologies), the DAE-6 solutions provide further design flexibility, including line-level and headphone-level audio outputs, and systems configurable from two channel to 9.1 channel.

The extended DSP programmability in the DAE-6 is enabled by a new release of the Audio Canvas control surface, significantly improving ease of use and configurability.

Audio Canvas III enables designers to configure their own audio signal flows and define the peripheral interfaces of the DAE-6, as well as provide for programming and optimisation of the final system solution with encryption available to ensure security and prevent reverse engineering.

Among the new processing capabilities that will be enabled in the DAE-6 range are the proprietary Mightycat functions that are associated with Mark Levinson’s system-level product tuning.

These blocks will be available for custom tuning by Mark Levinson, with a subset of these algorithms also available for additional tuning by system designers.

Intersil D2Audio makes the world’s only Intelligent Digital Amplifier, which is powered by the patented Digital Audio Engine (DAE).

It actively monitors the system and uses all-digital feedback technology to optimise the amplifier’s sound, delivering an immersive and flexible audio experience.

The D2Audio Class-D controller ICs are also highly customisable and are supported with a variety of application reference designs that allow manufacturers to add their own distinct sound and differentiable features through the on-chip DSP capability.

D2Audio amplifiers can be found inside consumer, commercial, professional and automotive audio equipment.
