HSP43124 - Serial I/O Filter

NAME VCC GND DIN TYPE I +5V Power Supply Ground Serial Data Input. The bit value present on this input is sampled on the rising edge of SCLK. A “HIGH” on this input represents a “1”, and a low on this input represents “0”. The word format and operation of serial interface are contained in the Data I.

HSP43124 Data Sheet May 1999 File Number 3555.6 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 b.
