Overview
The MC10EP32DR2G, produced by onsemi, is an integrated B2 divider with differential ECL (Emitter-Coupled Logic) clock inputs. This device is part of the MC10/100EP32 series, which operates in both PECL (Positive ECL) and NECL (Negative ECL) modes. It features an internally generated reference voltage (VBB) and an asynchronous reset pin, allowing for synchronization of multiple devices in a system. The MC10EP32DR2G is designed for high-speed applications, offering a typical propagation delay of 350 ps and a maximum frequency of over 4 GHz.
