Overview
The MC10EL32DG, produced by onsemi, is an integrated 2 divider designed for high-speed applications. This device features differential clock inputs and an internally generated reference voltage (VBB) that allows for differential, single-ended, or AC coupled interfaces. The VBB pin can be used to rebias AC coupled inputs and serves as a switching reference voltage for single-ended input conditions. The reset pin is asynchronous and is asserted on the rising edge, enabling the synchronization of multiple EL32 devices in a system. The 100 Series of this device includes temperature compensation, enhancing its performance across various operating conditions.
