XVF3000-TQ128-C

Overview

The XVF3000-TQ128-C is a programmable voice processing chip designed for hands-free communication in far-field environments. It features four-microphone adaptive beamforming, supporting both circular and linear array configurations. The device provides full-duplex operation with acoustic echo cancellation (AEC) optimized for interruptions up to 50dB and noise suppression optimized up to 15dB. It interfaces via high-speed USB 2.0 as a multi-channel UAC 1.0 device, supporting sampling rates of 16kHz and 48kHz. The component is housed in a 128-pin TQFP package and does not include built-in wake-word trigger detection.

Feature Summary

• Four-microphone adaptive beamforming for circular and linear arrays
• Full-duplex AEC with up to 50dB optimization for interruption support
• Noise suppression optimized up to 15dB
• High-speed USB 2.0 interface with multi-channel UAC 1.0 support

Applications

• Far-field voice interaction devices
• Hands-free communication systems
• Smart home audio controllers

Procurement Notes

Verify the specific suffix '-C' against official XMOS documentation to confirm manufacturing revision or binning details. Ensure compatibility with required USB audio class drivers and confirm that the absence of hardware wake-word detection aligns with system architecture requirements.

Selection Notes

Select this model when implementing multi-microphone beamforming without integrated wake-word detection. Verify that the host system supports USB 2.0 high-speed data transfer and UAC 1.0 protocols. Confirm that the 128-pin TQFP package fits the PCB layout constraints.

Part Context

The XVF3000 series belongs to XMOS's portfolio of programmable voice processors. Unlike later generations such as the XVF3610 which integrate AI-based algorithms, the XVF3000 focuses on deterministic DSP tasks like beamforming and echo cancellation, requiring external processing for advanced speech recognition logic.

Replacement Considerations

For direct functional replacement, verify availability of the base XVF3000 variant. Note that newer models like the XVF3610 offer enhanced performance but may require firmware re-engineering due to architectural differences in algorithm integration.
