The ADN4654/ADN4655/ADN4656¹ are signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 1.1 Gbps with low jitter. The devices integrate Analog Devices, Inc., iCoupler^® technology, enhanced for high speed operation to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This integration allows drop-in isolation of an LVDS signal chain.

The ADN4654/ADN4655/ADN4656 comprise multiple channel configurations, and the LVDS receivers on the ADN4655 and ADN4656 include a fail-safe mechanism to ensure a Logic 1 on the corresponding LVDS driver output when the inputs are floating, shorted, or terminated but not driven.

For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5 V supply. An integrated on-chip low dropout (LDO) regulator can provide the required 2.5 V from an external 3.3 V power supply. The devices are fully specified over a wide industrial temperature range and come in a 20-lead, wide body SOIC_W package with 5 kV rms isolation or in a 20-lead SSOP package with 3.75 kV rms isolation.

Applications

Isolated video and imaging data
Analog front-end isolation

Product Details

The EVAL-ADN4654EB1Z, the EVAL-ADN4655EB1Z, and the EVAL-ADN4656EB1Z allow quick and easy evaluation of the ADN4654/ADN4655/ADN4656 low voltage, differential signaling (LVDS) isolators without the need for external components. The ADN4654/ADN4655/ADN4656 employ Analog Devices, Inc., iCoupler^® technology to combine a 2-channel isolator with an LVDS receiver and driver into a single, 20-lead wide body SOIC package. The devices are capable of running at data rates of up to 1.1 Gbps with low jitter.

The evaluation boards have separate ground and power planes for each side of the isolator. This separation enables the evaluation of the ADN4654/ADN4655/ADN4656 with galvanic isolation between both sides of the device. Jumper-selectable power supplies at 3.3 V or 2.5 V are required on each side of the ADN4654/ADN4655/ADN4656 device. Using an on-chip, low dropout (LDO) regulator, 2.5 V can be provided from an external 3.3 V power supply.

Complete information about the ADN4654/ADN4655/ADN4656 is available in the ADN4654/ADN4655/ADN4656 data sheet. Consult this data sheet in conjunction with this user guide when using the evaluation boards.
