LTC6754HUD#PBF developed by Linear Technology/Analog Devices is a type of a high-speed rail-to-rail comparator with LVDS-compatible outputs. Instability can be minimized based on 4.5mV of hysteresis. It is ideally suitable for timing critical applications due to the dispersion of only 1ns combined with an excellent propagation delay of 1.8ns. Moreover, as a result of the 890Mbps toggle rate and low jitter of 1.5psRMS (200mVP–P, 245.76MHz input), this device is able to provide optimum performance for high-frequency line driver and clock recovery circuits.
