LTC6752HUD-3#PBF

LTC®6752 is a very high-speed comparator capable of supporting toggle rates up to 280MHz. It exhibits low propagation delays of 2.9ns and fast rise/fall times of 1.2ns. It has rail-to-rail inputs that operate from 2.45V, up to 3.5V or 5.25V, depending on the option. The outputs are CMOS and the separate supply options can operate down to 1.71V, allowing for directly interfacing to 1.8V logic devices. The low propagation delay of only 2.9ns combined with low dispersion of only 1.8ns (10mV to 125mV overdrive variation) makes this as an excellent choice for critical timing applications. Similarly, the fast toggle rate and low jitter of 4.5ps RMS (100mVP-P, 100MHz input) make LTC6752 ideally suited for high frequency line driver and clock recovery circuits. Applications includes clock and data recovery, level shifting, high speed data acquisition systems, window comparators, high speed line receivers, fast crystal oscillators, time of flight measurements and time domain reflectometry.
