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, or CK_IN can be divided down from FIR_CK. CK_IN is a CMOS .
