CS47L90-CWZR Allgemeine Beschreibung

The CS47L90 is a low power, highly integrated smart audio codec that features a programmable 975 MIPS seven-core DSP. The CS47L90 can support multiple audio features in parallel and launches the introduction of Cirrus Logic SmartHIFI™ for mobile playback devices. A high performance 4-channel ADC/8-channel DMIC, 24-bit high fidelity codec is embedded with SoundClear® software technology highlighted by 'always on, always listening' seamless multi-trigger word detection that does not require the applications processor to remain awake, thus conserving standby-mode power. SmartHIFI is a unique combination of powerful DSP processing and audio performance to deliver an audio experience typically associated with high-end audio equipment but now optimized for mobile audio playback while maximizing battery life. In addition to leading specifications for typical audio parameters such as THD, SNR, etc, SmartHIFI includes high-end features such as tunable hi-fi filters, jitter-free audio, high sample rate and bit depth support (24/32bit, 192kHz). The CS47L90 also features multi-mic wideband noise reduction, high performance acoustic-echo cancellation (AEC), mono active noise cancellation (ANC), speech enhancements, and advanced media applications.
