Selecting PLLs for ASIC Applications requires tradeoffs
News & Analysis 9/25/2003 Post a comment
PLLs, like many other analog IP macros, come with many features and specifications. Selecting the correct PLL early in the design can help the design team make tradeoffs when they are less costly, improve the integration quality of the PLL, and avoid surprises close to tapeout. From the September PA magazine folio, a True Circuits expert gives this assessment of what you should look for.
VXS: Switched Serial Gigabit Fabric for VMEbus
