1. Clock resource Overview The clock facility provides a series of low-capacitance, low-jitter Interconnect Lines that are ideal for transmitting high-frequency signals and minimizing clock jitter. These connection resources can be connected to DCM, PLL, and so on. Each Spartan-6 Chip provides 16 high-speed, low-jitter global clock resources to optimize performance. These resources can be automatically used by Xilinx tools, even if the clock frequency
