ADN4651 LVDS Digital Isolators

Analog Devices ADN4651 low-voltage differential signal (LVDS) digital isolators are designed using the iCoupler® digital isolator technology for high-speed operation. With this technology, the ADN4651 isolators offer galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. The design of the ADN4651 series allows for drop-in isolation of an LVDS signal chain. The isolators operate with data rates up to 600Mbps, 70ps ultra-low jitter, and 4.5ns max. The isolators include a fail-safe mechanism to ensure a logic 1 on the corresponding LVDS driver output when the inputs are floating, short circuit, or terminate. The devices are specified for operation over a −40°C to +125°C industrial temperature range with 5kVrms isolation and 7.6mm creepage/clearance. The ADN4651 isolators are well-suited for analog front end (AFE) isolation, data-plane isolation, isolated high-speed clock and data links, and isolated SPI over LVDS.
