1.0 General Description
BelaSigna 200 is a high-performance, programmable, mixed-signal digital signal processor (DSP) that is based on ON Semiconductor’s patented second-generation SignaKlara technology. This single-chip solution is ideally suited for embedded applications where audio performance, low power consumption and miniaturization are critical. BelaSigna 200 targets a wide variety of digital speech- and audio-centric applications, including: Communication headsets Smart phones Personal digital assistants (PDAs) Hands-free car kits Bluetooth wireless technology systems
BelaSigna 200 provides numerous analog and digital interfaces including parallel, serial, synchronous, and asynchronous interfaces to facilitate the connection with transducers from various applications. BelaSigna 200 contains two primary processing blocks, which all work together to provide a complete audio processing chain. The analog section includes two 16-bit A/D converters and two 16-bit D/A converters. Two on-chip direct digital output stages allow BelaSigna 200 to drive various output transducers directly, eliminating the need for external power amplifiers. BelaSigna 200 features internal clock generation and power regulation for excellent noise and power performance. Two DSP subsystems operate concurrently: the RCore, which is a fully programmable DSP core, and the weighted overlap-add (WOLA) filterbank coprocessor, which is a dedicated, configurable processor that executes ……
