DESCRIPTION
GB3211 / GB3221
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 thinSTAXTM packaging enables easy integration into BTE applications. This versatile DSP hybrid is capable of multiple configurations and has a wide range of functions. 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. For a detailed description of the POR behaviour of the GC5051 and GC5057 controller chips, please refer to PARAGONTM DIGITAL Reference Guide, Document #20143. The GB3211 and the GB3221 hybrid code programmed into the GC5051 and the GC5057 controller chips is "7". This data sheet is a part of a set of documents available for this product. Please refer to Getting Started with PARAGONTM DIGITAL" information note for a list of other documents.
