Best-in-class audio processor for IoT applications

Microsemi has announced its Timberwolf audio processor, the ZL38AMB. It is designed specifically for Ambarella camera SoCs and is claimed to be engineered to be the best-in-class HD audio solution for Ambarella's suite of video processors.

The ZL38AMB device is designed with AcuEdge Acoustic Technology on Microsemi's Timberwolf DSP platform, which features a set of complex, fully integrated algorithms that allow users to extract information from the audio environment in which they are communicating.

The audio processor is a wideband acoustic echo canceller which also provides noise reduction, beam forming and sound location detection for the IP camera and wearable markets.

The ZL38AMB is said to provide voice specific hardware accelerators, three digital microphone interfaces, two independent 16bit D/A converters with headphone drivers and two flexible time-division multiplexing interfaces in a single 64pin QFN or 56pin 3 x 3mm CSP. Additional features include 48kHz stereo music playback with voice, ultra-low and standby power.
