ADN4624 5.7 kV RMS/1.5 kV RMS, Quad-Channel LVDS 2.5 Gigabit Isolator (0 Reverse Channels)

Product Details

The ADN4624 is a quad-channel, signal isolated, low voltage differential signaling (LVDS) buffer that operates at up to 2.5 Gbps with very low jitter. The device integrates 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 ADN4624 includes a refresh mechanism to monitor the input and output states and ensure they remain the same in the absence of data transitions (for example, at power-on).

For lower power consumption and high speed operation with low jitter, the LVDS and isolator circuits rely on 1.8 V supplies. The ADN4624 is fully specified over a wide industrial temperature range and is available in a 28-lead, wide-body, finer pitch SOIC_W_FP 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).
