Configuration Specification  
FPP Configuration Timing  
This section describes the fast passive parallel (FPP) configuration timing parameters  
for Arria V devices.  
DCLK-to-DATA[] Ratio (r) for FPP Configuration  
FPP configuration requires a different DCLK-to-DATA[]ratio when you turn on  
encryption or the compression feature.  
Table 2–38 lists the DCLK-to-DATA[]ratio for each combination.

Note to Table 2–38:  
(1) Depending on the DCLK-to-DATA[]ratio, the host must send a DCLKfrequency that is r times the DATA[]rate in  
byte per second (Bps) or word per second (Wps). For example, in FPP x16 where the r is 2, the DCLKfrequency  
must be 2 times the DATA[]rate in Wps.  
FPP Configuration Timing when DCLK to DATA[] = 1  
Figure 2–5 shows the timing waveform for a FPP configuration when using a MAX® II  
device as an external host. This timing waveform shows timing when the DCLK-to-  
DATA[]ratio is 1.

When you enable decompression or the design security feature, the DCLK-to-DATA[]  
ratio varies for FPP x8 and FPP x16. For the respective DCLK-to-DATA[]ratio, refer to  
Table 2–38.
