NEW  AK7759VN
Voice processor for automotive telematics control unit

AK7759VN An increasing number of vehicles are equipped with a telematics control unit (TCU) that can place a hands-free (HF) eCall, enabling quick assistance in the event of an emergency. The AK7759 includes a DSP that provides voice processing for TCU applications, as well as analog I/O. The DSP can run AKM's original automotive HF processing software, providing a high-performance noise/echo canceller that complies with HF standards.
● Enables voice processing for hands-free eCall
● Support for a wide range of interfaces
● Voice processor compliant with HF standards
● Package: 36-pin QFN (6 x 6mm, 0.5mm pitch)

NEW  AK7739VQ
High resolution DSPs for audio and voice processing

AK7739VQ AKM's audio processors have been updated for scenarios such as listening to wireless sound at home or while driving and talking on a hands-free call. A 32-bit audio DSP supporting floating point arithmetic adopts, “VELVET SOUND”, technology established with high-end audio products.
The AK7739 is capable of processing sound and voice such as for hands-free function simultaneously because two DSPs are able to work on different but synchronized sampling frequencies. The automotive grade AK7739VQ that integrates a CODEC and the AK7737VQ with ADC are both now available to the market.
● Updating Established Dedicated DSP Audio
● VELVET SOUND Technology (AK7739)
● Building a Flexible Audio System
● Package: 64-pin HTQFP (10 x 10mm, 0.5mm pitch)

AK7604VQ
Audio processer for automotive head-units supporting playback of high resolution sound sources

AK7604VQ AK7604 is an audio processor optimized for processing high resolution music sources in automotive sound systems.  A portion of the specifications from the DSP core, Audio I/O, A/D converter, and D/A converter of the AK7738 were adopted in the AK7604.
Features were optimized and slimmed down, using only the necessary blocks for audio in the AK7604.  The part is suitable for car audio/navigation systems in entry or consumer classes. This is a successor to the AK7602.
● 28-bit pseudo floating-point arithmetic achieves various sound effect processes
● Audio processing parameters can be adjusted easily
● Audio systems can be built flexibly
● Package: 48-pin LQFP (7 x 7mm, 0.5mm pitch)

AK7707VQ
Multi Core DSP with Digital Audio Hub

AK7707VQ As it is a multi-core DSP (Digital Signal Processor), AKM’s original simple voice recognition algorithm can be used.  A high performance noise canceller and echo canceller process can be used simultaneously, including the addition of surround sound.  In addition, the AK7707 includes six asynchronous stereo SRC’s.
● High Performance HiFi 2 Core and AKM’s Original DSP Core
The 7707 integrates a one HiFi 2 DSP by Cadence and two of AKM’s original DSPs that process sample by sample.
● Supporting Multi Channels by Digital Audio Hub and SRC
The AK7707 has multiple clock settings, six asynchronous SRCs, and eight TDM supporting ports for each input and output, (Input: max 64ch, Output: max 64ch, in TDM Mode).
● Heat Dissipation in a Small Package
The AK7707 is housed in a 64-pin HTQFP package (10mmx10mm), which is suitable for compact system design with its good head dissipation.
