GB3211/GB3221 PRELIMINARY DATA SHEET

FEATURES

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, over-

sampled 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

• also available as E1 (RoHS Compliant Hybrid)

This data sheet is a part of a set of documents available for

this product. Please refer to Getting Started with

PARAGON™ DIGITAL” information note for a list of other
