Overview
The ADN4650BRWZ, produced by Analog Devices Inc., is a signal isolated, low voltage differential signaling (LVDS) buffer. This device operates at data rates of up to 600 Mbps with very low jitter, making it suitable for high-speed applications. The ADN4650 series integrates Analog Devices' iCoupler® technology, which provides galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This isolation is crucial for protecting components from dangerous voltages and currents, ensuring reliable and safe operation in various environments.
