Introduction

DSA504RT is a 6-output programmable clock generators for space applications. It integrates a low-jitter APLL,

two fractional dividers with spread spectrum, and two integer dividers in order to generate a wide range of

frequencies that can be applied to any of the six outputs using a cross-point switch and a back-end divider

in each output buffer for more frequency granularity. It uses an external differential/single-ended clock as

a reference that allows the synchronization of the outputs with the system’s general clock. The outputs can

be configured as 6 differential outputs (LPHCSL, LVPECL or LVDS), 12 LVCMOS outputs or a combination of

differential and single-ended ones.
