Table 1–6. Stratix Compression Ratios
The configuration clock (DCLK) speed is user programmable. One of two clock sources
can be used to synthesize the configuration clock; a programmable oscillator or an
external clock input pin (EXCLK). The configuration clock frequency can be further
synthesized using the clock divider circuitry. This clock can be divided by the N
counter to generate your DCLK output. The N divider supports all integer dividers
between 1 and 16, as well as a 1.5 divider and a 2.5 divider. The duty cycle for all clock
divisions other than non-integer divisions is 50% (for the non-integer dividers, the
duty cycle will not be 50%). Refer to
divider unit.
Figure 1–5. Clock Divider Unit
The DCLK frequency is limited by the maximum DCLK frequency the FPGA supports.
The maximum DCLK input frequency supported by the FGPA is specified in the
appropriate FPGA family chapter in the
