DEVICE OVERVIEW
The GF9105A is a drop in replacement for the GF9105 with lower power and increased functionality. This increased functionality gives the user the option of having HVF output signals and the option of using a low frequency clock when operating with non-multiplexed input and output data. The GF9105A is a flexible VDSP engine capable of performing a variety of format conversions. The flexible architecture of the GF9105A also allows the user to perform a wide range of DSP functions that require a general 3X3 multiplier structure and/or high performance 1:2 interpolation and 2:1 decimation filters. Device configuration is selected by writing configuration words through an asynchronous parallel interface (HOST IF).
