Overview
The MC100EP33DG is an integrated divide by 4 divider produced by onsemi. This component features differential clock inputs and is part of the 100 Series, which includes temperature compensation. The device is designed to operate in both PECL (Positive ECL) and NECL (Negative ECL) modes, making it versatile for various high-speed applications. The VBB pin provides an internally generated voltage supply that can be used as a switching reference voltage or to rebias AC coupled inputs. The reset pin is asynchronous and allows for the synchronization of multiple EP33 devices in a system.
