DESCRIPTION
The GB3215 (GB3225) hybrid is a programmable DSP
system based on a multi-channel compression circuit. It
can be used as a platform for a wide range of hearing aid
applications. Its extensive programmability and compact
size make it ideal for sophisticated CIC applications. The
reflowable thinSTAX packaging enables easy integration
into BTE applications. This very versatile DSP hybrid is
capable of multiple configurations and has a wide range of
functions.
The GB3215 hybrid contains the GC5051 controller chip
and the GA3225 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
