NB6N239S
NB6N239S is 3.3 V, 3.0 GHz Any Differential Clock IN to LVDS OUT Clock Divider manufactured by onsemi.
3.3 V, 3.0 GHz Any Differential Clock IN to LVDS OUT ÷1/2/4/8, ÷2/4/8/16 Clock Divider
Description The NB6N239S is a high- speed, low skew clock divider with two divider circuits, each having selectable clock divide ratios; B1/2/4/8 and B2/4/8/16. Both divider circuits drive LVDS patible outputs. (More device information on page 7). The NB6N239S is a member of the ECLin PS MAX™ family of high performance clock products.
