Overview
The ADN4655BRWZ, produced by Analog Devices Inc., is a signal isolated, low voltage differential signaling (LVDS) buffer designed for high-speed applications. This device integrates Analog Devices' iCoupler® technology, which provides galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This integration allows for drop-in isolation of an LVDS signal chain, ensuring optimal performance and reliability. The ADN4655BRWZ operates at up to 1.1 Gbps with low jitter, making it suitable for various high-speed data transmission applications.
