Overview
The ADN4650BRWZ-RL7 is a high-performance digital isolator produced by Analog Devices Inc. This device is designed to provide galvanic isolation for low voltage differential signaling (LVDS) signal chains, operating at speeds of up to 600 Mbps with very low jitter. It integrates Analog Devices' iCoupler technology, which is enhanced for high-speed operation, ensuring reliable and isolated transmission of LVDS signals. The ADN4650BRWZ-RL7 is suitable for various applications requiring high-speed data isolation, including analog front-end (AFE) isolation, data plane isolation, and isolated high-speed clock and data links.
