High speed comparators are often used in digital systems to recover distorted clock waveforms. The separate input/ output supplies feature of the LTC6752-2 allows it to be used in applications where signals need to be shifted from one voltage domain to another. The circuit above can perform both recovery and level translation functions. In this application, the input clock signal comes from a source operating from 5V, and the signal is required to drive a receiver operating on 1.8V. The 5V input supply/1.8V output supply feature of this part is ideal for such a situation. If the input signal gets distorted and its amplitude severely reduced due to stray capacitance, stray inductance or due to reflections on the transmission line, the LTC6752-2 can be used to convert it into a full scale digital output signal that can drive the receiver.
