Decimating Digital Filter
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.
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.
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.
