Description

General part information

LTC6754 Series

The LTC6754 is a high speed rail-to-rail comparator with LVDS compatible outputs. 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.In shutdown mode, power is reduced from 13.4mA to under 1.1mA, and the comparator can wake up in 120ns.The LTC6754 includes 4.5mV of hysteresis to minimize instability. For the QFN package, a separate pin is available to set the hysteresis from 0mV (off) up to 40mV. The QFN version also features output latching to provide the ability to quickly capture the state of the comparator.The dispersion of only 1ns combined with excellent propagation delay of 1.8ns makes the device an excellent choice for timing critical applications. Similarly, the 890Mbps toggle rate and low jitter of 1.5psRMS(200mVP–P, 245.76MHz input) make the LTC6754 ideally suited for high frequency line driver and clock recovery circuits.ApplicationsClock and Data RecoveryLevel TranslationHigh Speed Data Acquisition SystemsWindow ComparatorsHigh Speed Line ReceiversTime Domain ReflectometryTime of Flight MeasurementsCable Drivers
