Power PARAGON™ DIGITAL Four Channel DSP System with F RONTWAVE ® GB3211 PRELIMINARY DATA SHEET DESCRIPTION • high power applications The GB3211 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 code programmed into the GC5051 controller chip is “7”. • drives zero-bias 2-terminal receivers • multiple communication rates up to 85.3kb/s 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 documents. • multi-memory • internal/external volume control • volume control taper determined by external VC • 2 memory select pads • tri-state memory select operation • audible memory change indicator thinSTAX™ thinSTAX PACKAGING Hybrid typical dimensions: 0.227 x 0.125 x 0.060 in (5.76 x 3.18 x 1.52 mm) 205n VREG 7 FMIC 9 VB VC SDA MS MS2 VBP 12 5 4 11 13 14 GB3211 REGULATOR 13n A/D VC A/D INTERFACE EEPROM CHANNEL 1 70n FRONTWAVE CHANNEL 2 Σ 15 OUT+ 1 OUT- D/A HBRIDGE 70n RMIC 6 T 10 A/D CHANNEL 3 60n CHANNEL 4 MGND 8 All resistors in ohms, all capacitors in farads unless otherwise stated. 3 2 GND PGND BLOCK DIAGRAM Doc.No.20475 - 2 [Rev.
