Configuration Specification  
FPP Configuration Timing  
This section describes the fast passive parallel (FPP) configuration timing parameters  
for Cyclone 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 2–33 lists the DCLK-to-DATA[]ratio for each combination.

FPP (16-bit wide)  
Note to Table 2–33:  
(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 DCLK  
frequency must be 2 times the DATA[]rate in Wps.
