Overview
The MC100EL32DR2G is an integrated divide-by-2 divider produced by onsemi. This component is part of the 100 Series and features differential clock inputs along with a VBB pin, allowing for differential, single-ended, or AC coupled interfaces. The VBB pin serves as an internally generated reference voltage and should be bypassed to ground with a 0.01 μF capacitor if used. The device includes an asynchronous reset pin that is asserted on the rising edge, enabling the synchronization of multiple EL32 devices in a system. The 100 Series also includes temperature compensation for stable operation across various temperatures.
