AK7017VQ

Digital Signal Processor Dsp Overview

The AK7017VQ is a highly integrated digital signal processor designed for audio and voice processing applications. It features a single Tensilica HiFi4-a DSP core operating at 491.52MHz, optimized for C-language programming. The device integrates 8 stereo and 4 monaural sampling rate converters (SRCs) supporting frequencies up to 192kHz. It includes dedicated Digital Input Receiver (DIR) and Digital Input Transmitter (DIT) blocks with S/PDIF and AES/EBU compatibility. The chip provides extensive digital interface capabilities with 11 input and 11 output ports, supporting asynchronous IIS/TDM formats for up to 152 channels.

Digital Signal Processor Dsp Feature Summary

• Single-core Tensilica HiFi4-a DSP architecture with 64-bit word length and 491.52MHz operation clock
• Integrated SRC subsystem comprising 8 stereo (32-bit) and 4 monaural (24-bit) converters
• Built-in DIR and DIT supporting S/PDIF, IEC60958, and AES/EBU standards with de-emphasis filters
• 11-channel asynchronous digital audio interfaces supporting TDM modes with up to 152 channels

Digital Signal Processor Dsp Applications

• Multi-channel audio processing systems requiring parallel audio and voice handling
• Digital audio receivers and transmitters utilizing S/PDIF or AES/EBU inputs
• Embedded audio solutions using programmable acoustic effects via C-language development

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the HLQFP-100 pinout matches the target PCB layout requirements. Ensure power supply decoupling capacitors are placed close to VDDC, TVDD1, TVDD2, TVDD3, and AVDD pins as specified in the recommended external circuits section of the datasheet.

Digital Signal Processor Dsp Selection Notes

Select the AK7017VQ when a single high-performance DSP core is sufficient for the application load. This model is suitable for systems requiring simultaneous sampling rate conversion across multiple channels without the need for dual-core parallel processing found in higher-tier models like the AK7018. Verify that the required number of digital microphone inputs and serial data ports fits within the 11-port interface limit.

Digital Signal Processor Dsp Part Context

The AK7017VQ belongs to AKM's family of Audio Weaver-compatible DSP products, which also includes the dual-core AK7018 and the multi-core AK7709. These components share a common 100-pin HLQFP footprint, facilitating pin-compatible design upgrades. While the AK7017 utilizes a single HiFi4 core, it retains the same extensive peripheral set regarding SRCs and digital interfaces as its more powerful counterparts.

Digital Signal Processor Dsp Replacement Considerations

For direct pin-compatible replacements within the same product family, consider the AK7018VQ for dual-core performance or the AK7709VQ for additional AKM proprietary DSP cores. Ensure software migration strategies account for differences in memory allocation and core availability between the single-core AK7017 and these alternative models.
