ADI three SigmaDSP audio processor for high-end TV

In Electronic Infomation Category: R | on December   1, 2010

Analog Devices (ADI) has released three new SigmaDSP digital audio processors for advanced TV and LMV431ACM5X datasheet and audio systems (such as HDTV) and LMV431ACM5X price and multimedia player "portable" speaker systems on time and LMV431ACM5X suppliers and cost-sensitive consumer applications. New products include processor ADAV400, ADAU1701 and ADAU1702.


According to reports, the fastest SigmaDSP series DSP engine support, ADAV400 the 125MHz speed next-generation TV applications - high-definition television (HDTV) and flat-panel TV monitors a combination of technologies - audio processing requirements. The device will be 56-bit audio processing core with analog (ADC) and digital to analog converter (DAC) integrated, providing more than 95dB dynamic range. This allows HDTV provides improved audio experience can match the image quality. Chip also includes a delay memory function, dedicated to the compensation in the advanced TV video processing delay, thus ensuring full synchronization of video and audio signals. ADAV400 also supports 16 channels of digital I / O (I2S) to ensure maximum user flexibility.

ADAU1701 and ADAU1702 compared these two chips provides designers of 50MHz and 25MHz DSP engines, suitable for digital audio applications. IPod and MP3 player, for example, the docking stations, car radio and analog signal processing in the past to achieve full active speaker. Both devices integrate ADC and DAC, multi-channel digital I / O (I2S) port and delayed memory, and has a self-starting, external control and physical buttons and volume control interface functions without the need for a separate processor or MCU. These devices are also suitable with the ADIs Class D amplifier with AD199x series used to provide audio amplification and suppression of electromagnetic interference (EMI) capabilities.

In addition, the new graphical user interface SigmaDSP and SigmaStudio (GUI) design tool used to provide a fully automated hardware and software system design environment.

SigmaStudio DSP design tools without any programming knowledge, using a drag and drop interface that allows design engineers from the audio selection function module library (including volume controls, crossover filter and equalizer filters, and professional-grade dynamic processors) to establish multi-channel digital audio platform. SigmaStudio design tool also enables industry-standard algorithms licensed software such as SRS TruSurroundXTTM, Waves MaxxBass, Dolby Prologic-II or BBE-Viva.

ADAV400 product samples are available now. The device is lead-free 80-pin LQFP (small quad flat package), 10,000-unit quantities from $ 5.63 / piece from. Evaluation boards are currently available, including the SigmaStudio design tools, offer 699 U.S. dollars.

ADAU1701 with a 50MHz of the DSP, ADAU1702 with a 25MHz of the DSP, can now provide product samples, 48-pin LQFP lead-free package. 10,000-unit quantities, ADAU1701 3.72 USD / piece, ADAU1702 2.93 U.S. dollars / piece.
