DESCRIPTION
The LF3310 is a two-dimensional digital image filter capable of filtering data at real-time video rates. The device contains both a horizontal and a vertical filter which may be cascaded or used concurrently for two-dimensional filtering. The input, coefficient, and output data are all 12-bits and in two’s complement format.
