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