DESCRIPTION
The PL102 -10 is a high performance, low skew, low jitter zero dela y buffer designed to distribute high speed clocks and is available in 8 -pin SOP or 6 -pin SOT23 package . It has two outputs that are synchr onized with the input. The synchronization is established via CLKOUT feed back to the input of the PLL. Since the skew between the input and output is less than 350 ps, the device acts as a zero d elay buffer. BLOCK DIAGRAM PLLREFIN CLKOUT CLK1 CLK2 4 5 8REFIN CLK1 CLK2 CLKOUT DNC VDD DNCGND SOP-8L 3 4

Since CLKOUT is one of the inputs to the PLL, zero phase difference is maintained from REF to CLKOUT. If all outputs are equally loaded, zero phase difference will be maintained from REF to all outputs. If applications requiring zero output-output skew, all the outputs must be equally loaded. If the CLK(1-2) outputs are less loaded than CLKOUT, CLK(1-2) outputs will lead it; if the CLK(1-2) is more loaded than CLKOUT, CLK(1-2) will lag the CLKOUT. Since the CLKOUT and the CLK(1-2) outputs are identical, they all start at the same time, but difference loads cause them to have different rise times and different times crossing the measurement thresholds. CLK(1-2) Zero Delay REF CLKOUT CLK(1-2) Advanced REF CLKOUT CLK(1-2) Delayed REF input and all outputs are equally loaded REF input and CLK(1-2) outputs are equally loaded, with CLK(1-2) less loaded than CLKOUT. REF input and CLK(1-2) outputs loaded equally, withCLK(1-2) more loaded then CLKOUT.
