A new high-speed LVDS output comparator capable of toggle rates up to 890Mbps, the LTC6754 has been introduced by Linear Technology. The high-speed device operates with only 1.8ns of propagation delay, 1ns of overdrive dispersion, and 1.5psRMS of jitter. Combined, these features address the most challenging high speed applications for data acquisition, clock and data recovery and line receiving. The LTC6754 is fully specified for -40C to 125C, its quiescent current is only 13.4mA and it operates on a single supply from 2.4V to 5.25V. The voltage range at the two inputs extends beyond both supply rails, enabling the LTC6754 to be used for ground sensing applications. The LTC6754 is offered in two packages. The LTC6754 in the SC70 package provides a small and streamlined device. The LTC6754 in the 3mm x 3mm QFN package offers the same high speed performance with additional features, including adjustable hysteresis, latching capability, separate input and output supplies and shutdown. The LTC6754 drives LVDS interfaces either directly or through cables,” said Brian Hamilton, design manager, Linear Technology. “And its low propagation delay, low jitter and industry leading dispersion support blazingly fast signals.” The LTC6754 family is offered in the SC70 package and a 12-lead 3mm x 3mm QFN package. Both versions are offered in two temperature ranges: -40C to 85C and -40C to 125C.
