Decimating Digital Filter  
Features  
The HSP43220 Decimating Digital Filter is a linear phase  
low pass decimation filter which is optimized for filtering  
narrow band signals in a broad spectrum of a signal  
processing applications. The HSP43220 offers a single chip  
solution to signal processing applications which have  
historically required several boards of ICs. This reduction in  
component count results in faster development times as well  
as reduction of hardware costs.  
• Single Chip Narrow Band Filter with up to 96dB  
Attenuation  
• DC to 33MHz Clock Rate  
• 16-Bit 2’s Complement Input  
• 20-Bit Coefficients in FIR  
• 24-Bit Extended Precision Output  
• Programmable Decimation up to a Maximum of 16,384  
• Standard 16-Bit Microprocessor Interface  
• Filter Design Software Available DECIMATE™  
• Up to 512 Taps  
The HSP43220 is implemented as a two stage filter  
structure. As seen in the block diagram, the first stage is a  
high order decimation filter (HDF) which utilizes an efficient  
sample rate reduction technique to obtain decimation up to  
1024 through a coarse low-pass filtering process. The HDF  
provides up to 96dB aliasing rejection in the signal pass  
band. The second stage consists of a finite impulse  
response (FIR) decimation filter structured as a transversal  
FIR filter with up to 512 symmetric taps which can implement  
filters with sharp transition regions. The FIR can perform  
further decimation by up to 16 if required while preserving  
the 96dB aliasing attenuation obtained by the HDF. The  
combined total decimation capability is 16,384.  
Applications  
• Very Narrow Band Filters  
• Zoom Spectral Analysis  
• Channelized Receivers  
• Large Sample Rate Converter  
The HSP43220 accepts 16-bit parallel data in 2’s  
complement format at sampling rates up to 33 MSPS. It  
provides a 16-bit microprocessor compatible interface to  
simplify the task of programming and three-state outputs to  
allow the connection of several ICs to a common bus. The  
HSP43220 also provides the capability to bypass either the  
HDF or the FIR for additional flexibility.
