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, F
S
/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 for3-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.
