The DSA504RT is a 6-output programmable clock generator for aerospace and defense applications. It integrates a low jitter APLL, two fractional dividers with spread spectrum, and two integer dividers to generate a wide range of frequencies that can be applied to any of the six outputs using a cross-point switch. The DSA504RT uses an external differential/single ended clock as a reference, allowing the synchronization of the outputs with system’s general clock. The outputs can be configured as 6 differential outputs (LP-HCSL, LVPECL, or LVDS) or 12 LVCMOS outputs or a combination of differential and single ended.
