Serial I/O Filter
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.
