Overview
The MC100EL32DR2 is an integrated divide-by-2 divider from onsemi, designed for high-speed applications. This device features differential clock inputs and a VBB pin, which allows for differential, single-ended, or AC coupled interfaces. The VBB pin serves as an internally generated voltage supply and can be used to rebias AC coupled inputs or as a switching reference voltage for single-ended inputs. The reset pin is asynchronous and is asserted on the rising edge, enabling the synchronization of multiple EL32 devices in a system. The 100 Series includes temperature compensation, ensuring stable operation across various temperatures.
