Dynamic Clock Select (DCS)
The DCS is a global clock buffer with smart multiplexer functions. It takes two independent input clock sources and
outputs a clock signal without any glitches or runt pulses. This is achieved regardless of where the select signal is
toggled. There are eight DCS blocks per device, located in pairs at the center of each side. Figure 2-13 illustrates
the DCS Block Macro.
Figure 2-13. DCS Block Primitive
Figure 2-14 shows timing waveforms of the default DCS operating mode. The DCS block can be programmed to
other modes. For more information about the DCS, please see the list of technical documentation at the end of this
data sheet.
