5.7 kV rms/1.5 kV rms, Quad-Channel LVDS 2.5 Gigabit Isolators (2 Reverse Channels)

The ADN4622/ADN4624 are quad-channel, signal isolated, low-voltage differential signaling (LVDS) buffers that operate at up to 2.5 Gbps with very low jitter. The devices 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).

The ADN4622/ADN4624 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 1.8 V supplies. The ADN4622/ADN4624 are fully specified over a wide industrial temperature range and are available in a 28-lead, wide-body, finer pitch SOICWFP package with 8.3 mm creepage and clearance (for 5.7 kV rms or 8 kVPEAK surge and impulse voltages and reinforced insulation at AC mains voltages) or 6 mm × 6 mm LFCSP package with 1.27 mm creepage and clearance (for basic/functional isolation).
