FEATURES  
DESCRIPTION  
The LF3310 is a two-dimensional digital the device and filtered without  
83 MHz Data Rate  
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 data sets interleaved together. The  
used concurrently for two-dimensional vertical filter can handle interleaved  
filtering. The input, coefficient, and  
output data are all 12-bits and in twos data values. The I/ D Registers and

data streams. The horizontal filter  
can handle a maximum of sixteen

using decimation to increase the  
number of filter taps in the horizontal  
filter. Decimation of up to 16:1 is  
supported.  
The horizontal filter is designed to take  
advantage of symmetric coefficient sets.  
When symmetric coefficient sets are  
used, the horizontal filter can be  
configured as a 16-tap FIR filter. When The device has on-chip storage for 256

The vertical filter is an 8-tap FIR filter  
with all required line buffers contained  
on-chip. The line buffers can store  
video lines with lengths from 4 to 3076
