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- Ω series resistor that improves the signal integrity at the load. The CDC2586 operates at nominal 3.3-V VCC.
