14.2.2 Input and Output Signals

The following table lists the input and output ports of Sinc3 Filter.

Table 14-3. Inputs and Outputs of Sinc3 Filter
Signal NameDirectionDescription
reset_iInputActive low asynchronous reset signal to design
clk_adc_iInputModulator clock coming from ADC
data_adc_iInputData bitstream from the modulator in ADC
reg_rst_iInputWhen 1, resets all the registers. When 0, filter is normally operated.
clk_dec_oOutputDecimated clock output. This is the same clock used for differentiator. The output of the filter updates at the rising edge of this output. This signal is not generated when res_rst_i is high.
data_oOutputFiltered data output
