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, fine pitch SOIC-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).

Evaluation Kits (1)
The EVAL-ADN4624EB1Z allows quick and easy evaluation of the ADN4624 low voltage differential signaling (LVDS) isolator without the need for external components. The ADN4624 employs Analog Devices, Inc., iCoupler® technology to combine a 4-channel isolator with LVDS receivers and drivers into a single, 28-lead wide body SOIC package with finer pitch. The device is capable of running at data rates of up to 2.5 Gbps with low jitter.
The evaluation board has a separate ground and power plane for each side of the isolator. This separation enables the evaluation of the ADN4624 with galvanic isolation between both sides of the device. 1.8 V power supplies are required on each side of the ADN4624 device.
For full details on the ADN4624, see the ADN4624 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADN4624EB1Z.
