FEATURES

DESCRIPTION

ꢀ 83 MHz Data Rate

The LF3310 is a two-dimensional digital without separating the data into indi-

image filter capable of filtering data at

real-time video rates. The device con-

tains both a horizontal and a vertical

filter which may be cascaded or used

concurrently for two-dimensional filter- leaved video lines which contain

ing. The input, coefficient, and output 3076 or less data values. The I/D

data are all 12-bits and in two’s comple- Registers and horizontal accumulator

vidual data streams. The horizontal

filter can handle a maximum of six-

teen data sets interleaved together.

The vertical filter can handle inter-
