Power PARAGON™ DIGITAL Four Channel DSP System with FRONTWAVE ® GB3211/GB3221 PRELIMINARY DATA SHEET DESCRIPTION • high power applications The GB3211 (GB3221) hybrid is a programmable DSP system based on a multi-channel compression circuit. This hybrid is designed for low impedance receivers. It can be used as a platform for a wide range of hearing aid applications. It also offers a seperate supply line to the A/D and H-Bridge circuits. The reflowable thinSTAX™ packaging enables easy integration into BTE applications. This versatile DSP hybrid is capable of multiple configurations and has a wide range of functions. • highly configurable, versatile DSP platform • high fidelity multi-channel AGC signal processing • 95dB input dynamic range with HRX™ Headroom Extension • fully programmable via serial data interface • high performance data converters – dual, oversampled A/Ds; over-sampled D/A with efficient switched-mode output power amp The GB3211 hybrid contains the GC5051 controller chip and the GB3221 hybrid contains the GC5057 controller chip. The only difference between the GC5051 and the GC5057 is in their Power On Reset (POR) behaviour. • SOUNDDESIGN™ high-fidelity audio quality • drives zero-bias 2-terminal receivers • multiple communication rates up to 85.3kb/s • multi-memory For a detailed description of the POR behaviour of the GC5051 and GC5057 controller chips, please refer to PARAGON™ DIGITAL Reference Guide, Document #20143. • internal/external volume control • volume control taper determined by external VC • 2 memory select pads The GB3211 and the GB3221 hybrid code programmed into the GC5051 and the GC5057 controller chips is “7”. • tri-state memory select operation • audible memory change indicator This data sheet is a part of a set of documents available for this product.
