DESCRIPTION
The +5V power supply pins.
The device ground.
I 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 level signal.
I Input Clock for the FIR Filter. This clock must be synchronous with CK_IN. Operations in the FIR are synchronous with the
rising edge of this clock signal. The maximum clock frequency is 33MHz. FIR_CK is a CMOS level signal.
