The AK7738VQ is a 32-bit Floating-point Arithmetic High Performance Audio DSP with Additional Digital Signal Processing (DSP) Functionality and Flexible Configuration Options. It runs at a clock frequency of up to 49.152 MHz for efficient real-time audio processing, making it ideal for automotive sound systems, professional audio equipment, and consumer electronics. With its precision 256 MIPS (million instructions per second) throughput, it can process complex audio problems both quickly and accurately.
AK7738VQ also has a built-in programmable DSP core that supports custom audio processing algorithms, enabling differentiated products from manufacturers. The leading brands in the car audio space, for instance, rely on this chip to implement proprietary sound adjustments like noise cancellation or equalization and 3D surround. A 10-channel ADC and a 6-channel DAC enable the intervention of analog signal conversion, supporting up to 96 kHz and 102 dB (SNR) for high-resolution audio playback.
The power consumption in operation is below 100 mW which coincides with energy favourable design criteria that are important for automotive and portable applications. An easily configurable I/O methodology with four digital audio interfaces (DAI), allows designers to pair the DSP with other components in the system, such as microcontrollers or additional DSPs. This allows the AK7738VQ to serve as a complex audio signal routing hub in environments that have multiple sources.
The AK7738VQ combines an AEC function and beamforming, which are major functions demanded in automotive audio systems. With such features, they enhance hands-free communication and accuracy of in-car voice recognition, catering to the increasing demand for sophisticated human-machine interfaces (HMI) in advanced vehicles. Several firms, including Alpine and Pioneer, have integrated this very chip into their infotainment systems to provide users with enhanced experiences.
“Technology shouldn’t only be functional, it should be transformative,” said Masahiro Takahashi, an industry expert in digital signal processing (DSP) technology. An example of this is the AK7738VQ, which gives developers to flex their audio signal processing capabilities. The high programmability of VLSI makes it suitable for upcoming audio applications such as immersive virtual reality (VR) soundscapes and high-fidelity wireless audio transmission.
AK7738VQ seamlessly integrates with the most sophisticated DSP framework and toolkit to shorten development time while providing market-leading audio performance. To audio engineers, this combined strength and flexibility makes an ideal cornice-component for experimentation in crowded markets.
