High-speed LVDS output comparators toggle up to 890 Mbps

September 24, 2015 // By Graham Prophet
LTC6754 is a high speed LVDS output comparator capable of toggle rates up to 890 Mbps. This extremely fast comparator operates with 1.8nsec of propagation delay, 1 nsec of overdrive dispersion, and 1.5 psecRMS of jitter.

Taken together, Linear Technology asserts, 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 -40°C to 125°C, its quiescent current is 13.4 mA 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 3 x 3 mm QFN package offers the same high speed performance with additional features, including adjustable hysteresis, latching capability, separate input and output supplies and shutdown. LTC6754 drives LVDS interfaces either directly or through cables.

Both package options are offered in two temperature ranges: -40°C to 85°C and -40°C to 125°C, priced starting at $1.93 (1,000)
