Integrated Circuit Chip HSP43124SC-45Z - Intersil Corporation - Serial I/O Filter

Quick Detail:

Serial I/O Filter

Description:

The Serial I/O Filter is a high performance filter engine that is  ideal for off loading the burden of filter processing from a DSP  microprocessor. It supports a variety of multistage filter  configurations based on a user programmable filter and fixed  coefficient halfband filters. These configurations include a  programmable FIR filter of up to 256 taps, a cascade of from  one to five halfband filters, or a cascade of halfband filters followed by a programmable FIR. The half band filters each decimate by a factor of two, and the FIR filter decimates from one to eight. When all six filters are selected, a maximum decimation of 256 is provided.

For digital tuning applications, a separate multiplier is provided

which allows the incoming data stream to be multiplied, or mixed, by a user supplied mix factor. A two pin interface is provided for serially loading the mix factor from an external source or selecting the mix factor from an on-board ROM. The on-board ROM contains samples of a sinusoid capable of spectrally shifting the input data by one quarter of the sample rate, FS/4. This allows the chip to function as a digital down converter when the filter stages are configured as a low-pass filter.

The serial interface for 3- input and output data is compatible with the serial ports of common DSP microprocessors.

Coefficients and configuration data are loaded over a bidirectional eight bit interface.

Applications:

• 45MHz Clock Rate

• 256 Tap Programmable FIR Filter

• 24-Bit Data, 32-Bit Coefficients

• Cascade of up to 5 Half Band Filters

• Decimation from 1 to 256

• Two Pin Interface for Down Conversion by FS/4

• Multiplier for Mixing or Scaling Input with an External Source

• Serial I/O Compatible with Most DSP Microprocessors

• Pb-Free Plus Anneal Available (RoHS Compliant)
