DESCRIPTION
The LF43891 is a video-speed digital filter that contains eight filter cells (taps) cascaded internally and a shift-and-add output stage. A 9 x 9 multiplier, three decimation registers, and a 26-bit accumulator are contained in each filter cell. The output stage of the LF43891 contains a 26-bit accumulator which can add the contents of any filter stage to the output stage accumulator shifted right by 8 bits. 8-bit unsigned or 9-bit two’s complement format for data and coefficients can be independently selected.
