Chipidea Audio Codec IP Provides High Performance on Small Chip Area for Low Power Applications.


Portable Multimedia Applications Benefit from High-Quality Sound and Broad Range of Features

LISBON, Portugal -- Chipidea[R], the world's leading provider of analog/mixed-signal silicon intellectual property, today announced the most complete portfolio of audio codec IP for mobile applications. The IP exhibits a unique blend of audio features, audio performance and risk-free integration for System-on-Chip (SoC) devices and multi-chip modules (McMs) targeting mobile audio, communications and multimedia systems. The low power consumption and range of features included by this line of IP offer the semiconductor industry unprecedented versatility and ease of integration.

The most compelling features of Chipidea's audio solutions are the low power consumption, and very low area for a complete stereo codec (1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV,  featuring microphone, , line-in/out, headphone See headphones.  and speaker analog interfaces and high-fidelity audio performance up to 100dB in dynamic range. In addition, the codec IP is designed with sigma-delta technology, which has low sensitivity to interference and cross talk from power supplies and substrates.

Chipidea's audio family has two unique offerings: High-end, full-featured audio codec IP and optimized cost-performance audio codec IP. The high-end audio solutions offer both high-fidelity and full range of features including digital sound effects, jack detection, audio PLL PLL - phase-locked loop , and more. The variety of features enables the integration of audio functions on McMs and SoCs that were previously only available from standalone ICs.

The optimized cost-performance audio codec IP enables high-fidelity audio quality with multiple analog interface capabilities, such as microphone, line-in/out, headphone and loudspeaker. The IP is very compact in area at around 2.7mm2 to help SoC designers keep their die sizes small and keep manufacturing costs low. It also offers very low power consumption of 12mW for 96dB DR in playback at 48 kHz.

"Manufacturers need to deliver a high-quality audio experience while assuring long playback times for battery-operated devices, under competitive pricing in the market," said JoEuo Risques, product line manager of Audio and Power Management Solutions for Chipidea. "Our optimized cost-performance audio codecs are affordable SoC-ready IP meaning they are optimized for low area and low power while still allowing designers to select precisely the features they need. In addition, Chipidea can offer to designers high-end, hi-fi audio codecs that are directly comparable with market IC products from leading IC vendors, a solution that to our knowledge has no match in any other IP vendor portfolio."

Chipidea's staff has worked closely with customers to develop the new features in the latest generation of IP and they can be adapted for a wide variety of applications, which helps reduce risk in the integration process.

A full range of feature, cost and performance options gives Chipidea's audio codec IP the flexibility to be configured for the specific needs of any Integrated Device Manufacturer See IDM.  (IDM (1) See identity management.

Chipidea's audio codec IP is ideally designed for MP3 players and recorders, multi-format players and recorders (AAC (Advanced Audio Coding) An audio compression technology that is part of the MPEG-2 and MPEG-4 standards. AAC, especially MPEG-4 AAC, provides greater compression and better sound quality than MP3, which also came out of the MPEG standard. , WMA (Windows Media Audio) An audio compression method from Microsoft. Known originally as MSAudio, this proprietary format competes with the MP3 and AAC methods. WMA encodes rapidly and is known to be especially effective at low bit rates.  and others), CD and MiniDisc A compact digital audio disc from Sony that comes in read-only and rewritable versions. Introduced in late 1993, the MiniDisc has been most popular in Japan.

Designers can achieve fast time-to-market with Chipidea's audio codec IP family as it is available in several foundry process technologies ranging from 0.18-micron down to 65 nanometers. Previous generations of Chipidea codecs The following is a list of codecs. Audio codecs

The Chipidea CI7819pg is a high-end audio IP and the CI7825tl is an optimized cost-performance audio IP.
