Serial I/O Filter

Features

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.

• 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 F /4

• Multiplier for Mixing or Scaling Input with an External

Source

• Serial I/O Compatible with Most DSP Microprocessors

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

Applications

• Low Cost FIR Filter

• Filter Co-Processor

• Digital Tuner

quarter of the sample rate, F /4. This allows the chip to

function as a digital down converter when the ﬁlter stages

are conﬁgured as a low-pass ﬁlter.
