DESCRIPTION
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.
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
PARAGON? DIGITAL Reference Guide, Document
#20143.
The GB3211 and the GB3221 hybrid code programmed
into the GC5051 and the GC5057 controller chips is “7”.
