Overview
The ADN4650BRSZ-RL7 is a signal isolated, low voltage differential signaling (LVDS) buffer produced by Analog Devices Inc. This component is part of the ADN4650 series, which includes the ADN4650, ADN4651, and ADN4652 models. The ADN4650BRSZ-RL7 operates at data rates up to 600 Mbps with very low jitter, making it suitable for high-speed applications requiring galvanic isolation.
The device integrates Analog Devices' iCoupler® technology, which is enhanced for high-speed operation. This technology provides isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers, allowing for drop-in isolation of an LVDS signal chain.
