SoC Intellectual Property

As a result of ANAGRAMs investment in innovation and development of digital audio technology, ANAGRAM has created a highly focused portfolio of intellectual property (IP) for silicon providers that is available for licensing. This portfolio includes RTL or source code for all of our products and in addition we provide a full set of schematics, reference designs, and documentation.

Digital PureLogic™ SoC IP

ANAGRAM Digital PureLogic family of products allows SoC and system designers to integrate superior high definition digital and analog audio functions without the need for sensitive and difficult to integrate mixed-signal IP. By using only industry standard digital CMOS processes, Digital PureLogic technology accelerates time-to-market and reduces risk and cost in the development and manufacturing of on-chip digital audio subsystems.

SoftAMP offers SoC designers the possibility to build fully digital audio low and high level solutions by using a proprietary on-chip PWM modulator that directly drives low cost headphone amplifiers or switching power stages. It has been specifically optimized for consumer and automotive audio/video applications that require a small silicon area, quick time-to-market and ease of integration. In effect, SoftAMP reduces the systems bill of materials cost, weight, size, and power consumption associated in these applications and enables a fully digital audio path from the source to the speaker.

SoftDAC is a low complexity, high quality 24bit stereo digital-to-analog converter (DAC) designed for price sensitive, compact, and energy efficient consumer and automotive applications. It replaces traditional mixed-signal D/A converters by a proprietary on-chip fully digital PWM modulator and analog opamp based filter to provide line level outputs, drive wide-band analog power amplifiers or to directly power low impedance headphones. Minimal analog circuitry ensures the SoC designer has the most cost effective and lowest risk solution for each system design.

Q5 Sample Rate Converter acts as a cost effective front-end for consumer and automotive digital audio subsystems providing a unified output sampling frequency while decoupling asynchronous and synchronous time-domains for jitter free D/A conversion and PWM modulation. It provides completely transparent sample rate conversion for any standard audio PCM input sampling rates ranging from speech to DVD-Audio which can be completely asynchronous or synchronous to an external data clock.
