Overview
The ADN4654BRSZ-RL7, produced by Analog Devices Inc., is a signal isolated, low voltage differential signaling (LVDS) buffer. This device operates at speeds of up to 1.1 Gbps with low jitter, making it suitable for high-speed data transmission applications. It integrates Analog Devices' iCoupler® technology, which provides galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This allows for drop-in isolation of an LVDS signal chain, enhancing the reliability and safety of the system.
