Overview
The MC10EP33DG is an integrated B4 divider produced by onsemi. This component is part of the MC10/100EP33 series, designed to operate in both PECL (Positive ECL) and NECL (Negative ECL) modes. It features differential clock inputs and an internally generated voltage supply (VBB) for reference and rebiasing AC coupled inputs. The device includes an asynchronous reset pin to synchronize multiple dividers in a system and ensures that the internal flip-flops attain a defined state upon power-up. The MC10EP33DG is available in Pb-free packages, making it compliant with RoHS standards.
