XVF3610-QF60A-C

Overview

The XVF3610-QF60A-C is a microphone array processing chip from XMOS, designed for far-field voice interaction in smart devices. It integrates advanced DSP algorithms including acoustic echo cancellation (AEC), noise suppression (NS), and interference cancellation (IC) to enhance speech clarity in noisy environments. The device supports dual-microphone input via PDM interfaces and provides flexible audio output paths optimized for both Automatic Speech Recognition (ASR) and communication applications. It operates as a USB 2.0 Full-Speed device compatible with UAC 1.0 standards.

Feature Summary

• Integrated 2-Mic Array Algorithms: Combines AEC, IC, and NS for robust performance in complex acoustic environments.
• Dual Audio Output Paths: Simultaneously processes signals for ASR (enhanced SNR) and Communication (cleaner spectrum).
• Amazon AVS Certified: Validated for use in Alexa-enabled devices, ensuring compatibility with Amazon's voice services.
• Flexible Interface Support: Includes I2S, SPI, and I2C interfaces for system control and peripheral integration.

Applications

• Smart Speakers and Soundbars
• Video Conferencing Devices
• Smart Home Appliances
• Robotics Voice Interfaces

Procurement Notes

Verify the specific suffix 'QF60A-C' against official XMOS documentation to confirm pinout and voltage levels, as variations exist within the XVF3610 family. Ensure compliance with RoHS directives if required by your region. Check for available development kits like the P3610-2MIC for initial prototyping and algorithm validation before finalizing component selection.

Selection Notes

Select this model when a compact QFN-60 package is required for space-constrained designs. It is suitable for applications needing certified Amazon Alexa integration without external voice controllers. Compare power consumption specifications against battery-operated requirements, noting that integrated DSP reduces the need for secondary processors. Evaluate whether the built-in AEC and NS capabilities meet your specific noise environment needs versus custom DSP solutions.

Part Context

The XVF3610 series represents an evolution in XMOS VocalFusion technology, succeeding earlier models like the XVF3510. It offers improved performance and lower power consumption compared to predecessors. The QF60 package variant is specifically targeted at cost-sensitive and size-constrained consumer electronics, providing a complete software-defined solution for voice front-end processing.

Replacement Considerations

Direct replacements may include other XVF3610 variants with different suffixes if pin compatibility differs. For legacy systems, the XVF3510 serves as a predecessor but requires firmware adaptation. Cross-reference with newer XVF3620 if AI-based noise reduction features are prioritized over established AVS certification history.
