Overview
The MC10EL32DR2G, produced by onsemi, is an integrated 2 divider designed for high-speed applications. This device is part of the MC10EL/100EL32 series and features differential clock inputs, allowing for differential, single-ended, or AC coupled interfaces. The VBB pin provides an internally generated voltage supply, which can be used to rebias AC coupled inputs or as a switching reference voltage for single-ended inputs. The device includes an asynchronous reset pin, enabling the synchronization of multiple dividers in a system.
