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 SOIC_W_FP package with 8.3 mm creepage and clearance (for 5.7 kV rms or 8 kV_PEAK 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).

APPLICATIONS

Isolated video and imaging data
Analog front-end isolation

Product Details

The EVAL-ADN4622EB1Z and EVAL-ADN4624EB1Z allow quick and simple evaluation of the ADN4622 and ADN4624 low-voltage differential signaling (LVDS) isolators respectively, without the need for external components. The ADN4622/ADN4624 employ 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 devices are capable of running at data rates of up to 2.5 Gbps with low jitter.

The EVAL-ADN4622EB1Z and EVAL-ADN4624EB1Z have a separate ground and power plane for each side of the isolator. This separation enables the evaluation of the ADN4622/ADN4624 with galvanic isolation between both sides of the device. 1.8 V power supplies are required on each side of the ADN4622/ADN4624 device, and the ADN4622 additionally requires a 3.3 V power supply on each side.

For full details on the ADN4622/ADN4624, see the ADN4622/ADN4624 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADN4622EB1Z or EVALADN4624EB1Z.
