The basis for this configuration is:
Sampling Rate:
Select a high rate PROCCLK
Output Rate:
1.083MHz (4x Bit Rate; 8x Baud Rate)
CIC Filtering:
Primarily Rate Reduction (39/18 = 2.166MHz).
HB Filtering:
Flat passband with rate reduction by 4 - low
enough (541.66kHz) for sufficient FIR Taps to be used.
FIR Filtering:
Primary shaping filter/set final out of band
suppression.
Polyphase/HalfBand Filtering:
Interpolate by two to output
8x baud rate or 4x bit rate.
The CIC and halfband filter responses are shown in Figures
48A and B.
The composite filter response, constrained primarily by half-
band filter 5 and the FIR filter, are shown in Figure 45.
For a more detailed discussion of design approaches and
trades when designing with the PDC, refer to AN9720[3],
