0W344-004-XTP Product Details

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: 

ƒ Communication headsets 

ƒ Smart phones 

ƒ Personal digital assistants (PDAs)

 ƒ Hands-free car kits 

ƒ 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 time-frequency domain transforms and other vectorbased computations. In addition to these processors, there are several other peripherals, which optimize the architecture to audio processing, such as the onput/output processor (IOP) – an audio-targeted direct memory access (DMA) processor, which runs in the background and manages the data flow between the converters and the two processors.
