NEW 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.

AK7755EN
DSP with Mono ADC Stereo CODEC + Mic/Lineout

AK7755EN

The AK7755 is a highly integrated digital signal processor, including a mono ADC, a stereo audio CODEC, a MIC pre-amplifier, a line-out amplifier and digital audio I/F. The audio DSP has 2560step at fs = 48kHz parallel processing power. As the AK7755 is a RAM based DSP, it is programmable for user requirements such as high performance hands free function and acoustic effects. The AK7755 is available in a space saving small 36-pin QFN package.

AK7738VQ
Multi Core DSP with 5ch ADC, 4ch DAC, 8ch SRC

AK7738VQ

The AK7738 is an audio/voice digital signal processor that realizes high performance hands-free voice process in addition to audio process. Surround sound processing and high performance noise and echo cancellations can be executed simultaneously by the Multi Core DSP (Digital Signal Processor). This device integrates two stereo ADC’s (A/D converter), one monaural ADC, two stereo DAC’s (D/A converter) and four asynchronous SRC’s (Sample Rate Converter). Advanced 32-bit DAC’s are adopted for analog outputs, realizing a high-quality playback of high-resolution sound sources. The AK7738 is suitable for car audio, display audio, car navigation systems and hands-free systems.
