Overview
The ADN4654BRWZ-RL7, 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 to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. It operates at speeds of up to 1.1 Gbps with low jitter, making it suitable for various high-speed data transmission requirements. The ADN4654 is part of a family that includes multiple channel configurations and features an integrated on-chip low dropout (LDO) regulator to provide the necessary 2.5 V supply from an external 3.3 V power source.
