Dual 8-Tap FIR Filter  
DEVICES INCORPORATED  
FEATURES  
DESCRIPTION  
The LF43168 is a high-speed dual FIR  
filter capable of filtering data at real-  
time video rates. The device contains  
two FIR filters which may be used as  
two separate filters or cascaded to  
form one filter. The input and coeffi-  
cient data are both 10-bits and can be  
in unsigned, two’s complement, or  
mixed mode format.  
be implemented. The LF43168 can  
decimate the output data by as much  
as 16:1. When the device is pro-  
grammed to decimate, the number of  
clock cycles available to calculate filter  
taps increases. When configured for  
16:1 decimation, each filter can be  
configured as a 128-tap FIR filter (if  
symmetric coefficient sets are used).  
By cascading these two filters, the  
device can be configured as a 256-tap  
FIR filter.
