ANALOG DEVICES ADN4622BCPZ

ADN4622 is a quad-channel, signal-isolated, low-voltage differential signalling (LVDS) buffer that operate at up to 2.5Gbps with very low jitter. The device integrates Analog Devices, Inc., iCoupler® technology, enhanced for the high-speed operation to provide drop-in galvanic isolation of LVDS signal chains. AC coupling and/or level shifting to the LVDS receivers and from the LVDS drivers allows the isolation of other high-speed signals such as current-mode logic (CML). This include a refresh mechanism to monitor the input and output states and ensure they remain the same in the absence of data transitions. For lower power consumption and high-speed operation with low jitter, the LVDS and isolator circuits rely on 1.8V supplies. Application includes isolated video and imaging data, analogue front-end isolation, data plane isolation, isolated high speed clock and data links, multi-gigabit SERDES, and board-to-board optical replacement (for example, short reach fibre).
