Analog Devices Inc. ADN465x 5kV & 3.75kV LVDS Gigabit Isolators

Analog Devices ADN465x 5kV and 3.75kV LVDS Gigabit Isolators are signal-isolated, low voltage differential signaling (LVDS) buffers that operate at up to 1.1Gbps with low jitter. The devices integrate Analog Devices iCoupler® technology, enhanced for a high-speed operation to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This integration allows drop-in isolation of an LVDS signal chain. Analog Devices ADN465x 5kV and 3.75kV LVDS Gigabit Isolators comprise multiple channel configurations, and the LVDS receivers on the ADN4655 and ADN4656 include a fail-safe mechanism. This mechanism is to ensure a Logic 1 on the corresponding LVDS driver output when the inputs are floating, shorted, or terminated but not driven.
