ADN4656BRSZ

ADN4656BRSZ is a dual-channel, signal isolated, low voltage differential signaling (LVDS) buffer gigabit isolator that operate at up to 1.1Gbps with low jitter. The device integrates Analog Devices, Inc., iCoupler® technology, enhanced for 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. The ADN4656 comprise multiple channel configurations, and the LVDS receivers on the ADN4656 include a fail-safe mechanism to ensure a Logic 1 on the corresponding LVDS driver output when the input is floating, shorted, or terminated but not driven. For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5V supply. Application includes isolated video and imaging data, analog front-end isolation, data plane isolation, isolated high speed clock and data links.
