Overview
The MC10EL33DR2, produced by onsemi, is an integrated ÷4 divider designed for high-speed applications. This device is part of the MC10EL/100EL33 series, which supports differential, single-ended, or AC coupled clock inputs. The MC10EL33DR2 features an internally generated voltage supply (VBB) that can be used to rebias AC coupled inputs or serve as a switching reference voltage for single-ended inputs. The device includes an asynchronous reset pin, which is asserted on the rising edge, allowing for the synchronization of multiple dividers in a system. The 100 Series, to which this device belongs, includes temperature compensation for stable operation across various temperatures.
