All the outputs are distributed from a single clock input CLKIN and output OUT0 performs zero delay by connecting a feedback to PLL. Maximum rated frequency: 133 MHz Low cycle-to-cycle jitter Input to output delay, less than 200ps Internal feedback allows outputs to be synchronized to the clock input • Operates at 3.3V VDD • Space-saving Packages: (Pb-free & Green available) 150-mil SOIC (W) 173-mil TSSOP (L) PI6C2409-1 has two banks of four outputs that can be controlled by the selection inputs, SEL1 & SEL2. It also has a powersparing feature: when input SEL1 is 0 and SEL2 is 1, PLL is turned off and all outputs are referenced from CLKIN. PI6C2409-1 is available in high drive and industrial environment versions. An internal feedback on OUT0 is used to synchronize the outputs to the input; the relationship between loading of this signal and the outputs determines the input-output delay.
