The CDC2586 is a high-performance, low-skew, low-jitter clock driver. It uses a phase-lock loop (PLL) to precisely align, in both frequency and phase, the clock output signals to the clock input (CLKIN) signal. It is specifically designed for use with popular microprocessors operating at speeds from 50 MHz to 100 MHz or down to 25 MHz on outputs configured for half-frequency operation. Each output has an internal 26- series resistor that improves the signal integrity at the load. The CDC2586 operates at nominal 3.3-V VCC. The feedback input (FBIN) synchronizes the output clocks in frequency and phase to CLKIN. One of the twelve output clocks must be fed back to FBIN for the PLL to maintain synchronization between CLKIN and the outputs. The output used as feedback is synchronized to the same frequency as CLKIN.
