ADN4624BRNZ, Цифровой изолятор, 4 канал(-ов), 1.7 В, 1.9 В, WSOIC, 28 вывод(-ов), 2.5 Гбит/с

ADN4624 is a quad-channel, signal isolated, low voltage differential signalling (LVDS) buffer that operates at up to 2.5Gbps with very low jitter. The device integrate Analog Devices, Inc., iCoupler® technology, enhanced for 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 isolation of other high-speed signals such as current-mode logic (CML). It includes a refresh mechanism to monitor the input and output states and ensure they remain the same in the absence of data transitions. Safety and regulatory approvals are DIN V VDE V 0884-11 (VDE V 0884-11): 2017-01, VIORM=849 VPEAK (working voltage). Typical applications are isolated video and imaging data, Analog front-end isolation, data plane isolation, isolated high speed clock and data links, multi-gigabit SERDES, board-to-board optical replacement (for example, short reach fibre).
