HSP43220 - Decimating Digital Filter

NAME VCC GND CK_IN I TYPE The +5V power supply pins. The device ground. Input Sample Clock. Operations in the HDF are synchronous with the rising edge of this clock signal. The maximum clock frequency is 33MHz. CK_IN is synchronous with FIR_CK and thus the two clocks may be tied together if required.

HSP43220 Data Sheet February 1999 File Number 2486.7 Decimating Digital Filter The HSP43220 Decimating Digital Filter is a linear phase low pass decimation ﬁlter which is optimized for ﬁltering narrow band signals in a broad spectrum of a signal processing applications. The HSP43220 offers a single chip solution to signal processing applications which have historically required several boards of ICs. This reduction in component count results in faster development times as well as reduction of h.
