Overview
The MC100EP32DTR2G, produced by onsemi, is an integrated ÷2 divider with differential ECL (Emitter-Coupled Logic) clock inputs. This device is part of the MC10/100EP32 series, designed to operate in both PECL (Positive ECL) and NECL (Negative ECL) modes. It features a VBB pin, which provides an internally generated voltage supply, useful for rebiasing AC coupled inputs and serving as a switching reference voltage.
The device includes an asynchronous reset pin that allows for the synchronization of multiple EP32 devices in a system. It is available in various packages, including TSSOP-8, and is Pb-free, halogen-free, and RoHS compliant.
