Functional Description
Programmable Configuration Clock
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%). See
Figure 2–5
for a block
diagram of the clock divider unit.
Figure 2–5. Clock Divider Unit
The
DCLK
frequency is limited by the maximum
DCLK
frequency the
FPGA supports.
f
The maximum
DCLK
input frequency supported by the FPGA is
specified in the appropriate FPGA family chapter in the
Configuration
Handbook
.
