VP16256  
Programmable FIR Filter  
Advance Information  
Supersedes August 1997 version, DS4548 - 3.2  
DS4548 - 4.0 August 1998  
The VP16256 contains sixteen multiplier - accumulators, which  
canbemulticycledtoprovidefrom16to128stagesofdigitalfiltering.  
Input data and coefficients are both represented by 16-bit two’s  
complementnumberswithcoefficientsconvertedinternallyto12bits  
and the results being accumulated up to 32 bits.

ofupto40MHz. Ifalowersamplerateisacceptablethenthenumber  
ofstagescanbeincreasedinpowersoftwouptoamaximumof128.  
Each time the number of stages is doubled, the sample clock rate  
mustbehalvedwithrespecttothesystemclock.With128stagesthe  
sample clock is therefore one eighth of the system clock.  
In all speed modes devices can be cascaded to provide filters of  
anylength,onlylimitedbythepossibilityofaccumulatoroverflow.The  
32-bit results are passed between cascaded devices without any  
intermediate scaling and subsequent loss of precision.

The device can be configured as either one long filter or two  
separate filters with half the number of taps in each. Both networks  
can have independent inputs and outputs.

numberofstagesarepossibleatagivensamplerate.Asingledevice  
witha40MHzclockwouldthen,forexample,providea128-stagelow  
pass filter, with a 10MHz input rate and 5MHz output rate.  
Coefficients are stored internally and can be down loaded from  
a host system or an EPROM. The latter requires no additional  
support, and is used in stand alone applications. A full set of  
coefficientsisthenautomaticallyloadedatpoweron,orattherequest  
of the system. A single EPROM can be used to provide coefficients  
for up to 16 devices.
