The LTC6754 exhibits 1.8ns of propagation delay, only 1ns of dispersion (10mV to 125mV overdrive) and a toggle rate up to 890Mbps. The LTC6754 has rail-to-rail inputs, and will operate from a 2.4V to 5.25V supply. For the QFN package, the LVDS output is operated with a separate supply, providing isolation between input and output circuitry, and allowing for logic level translation. ...
