Additional Infomation About Product

STA321MPL1 Scalable digital microphone processor Datasheet - production data Description The STA321MPL1 is a PDM, high-performance, multichannel processor with ultra-low quiescent 74)3 PP PP current. It is designed for general-purpose digital microphone applications. The device is fully digital and is comprised of three main sections. Features The first section is the PDM input interface which can accept up to six serial digital inputs. The 8 digital processing channels each 24-bits second section is a high-quality audio processor 6 channels of PDM input allowing flexible channel mixing/muxing and provides up to 10 biquads for general sound 2 additional virtual channels equalization and voice enhancement with >100 dB SNR and dynamic range independent volume control. The last block is the Digital gain/attenuation 58 dB to -100 dB in IS output interface which streams out the 0.5 dB steps processed digital audio. The output interface can also be programmed for flexible channel Soft volume update mapping. The device offers some of the most Individual channel and master level control commonly required audio enhancements such as Up to 10 independent 32-bit user- programmable voice tuning and equalization, programmable biquads (EQ) per channel limiter/compressor for improved voice quality, multiband selection for customizable microphone Bass/treble tone control usage, and configurable wind-noise rejection. The Pre- and post-EQ full 8-channel input mix on all embedded digital processor allows the 8 channels microphone processing to be offloaded from the Dual independent limiters/compressors main CPU or SoC to the device. Dynamic range compression or anti-clipping The STA321MPL1 has six digital microphone modes inputs, providing connections for up to three dual- Individual channel and master soft/hard mute membrane microphones. 3 IS data outputs Table 1.
