Overview
The ADN4651BRWZ-RL7 is a digital isolator produced by Analog Devices Inc. This component is designed as a signal isolated, low voltage differential signaling (LVDS) buffer, operating at speeds of up to 600 Mbps with very low jitter. It integrates Analog Devices' iCoupler® technology to provide galvanic isolation of TIA/EIA-644-A compliant LVDS drivers and receivers. The device is particularly useful for applications requiring high-speed data transmission with robust isolation.
