Spartan-3 FPGAs
XAPP462 (v1.1) January 5, 2006


Summary Digital Clock Managers (DCMs) provide advanced clocking capabilities to Spartan-3 FPGA
applications. DCMs optionally multiply or divide the incoming clock frequency to synthesize a
new clock frequency. DCMs also eliminate clock skew, thereby improving system performance.
Similarly,
