Decimating Digital Filter

Features

The HSP43220/883 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 HSP43220/883 offers a single

chip solution to signal processing application 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.

• This Circuit is Processed in Accordance to MIL-STD-883

and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

• Single Chip Narrow Band Filter with up to 96dB

Attenuation

• DC to 25.6MHz Clock Rate

• 16-Bit 2’s Complement Input

The HSP43220/883 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 decimation (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.

• 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 DECI•MATE™

Applications

• Very Narrow Band Filters

• Zoom Spectral Analysis

• Channelized Receivers

Ordering Information

The HSP43220/883 accepts 16-bit parallel data in 2’s

complement format at sampling rates up to 30MSPS. 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

HSP43220/883 also provides the capability to bypass either

the HDF or the FIR for additional flexibility.
