Product Details

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
  • Data plane isolation
  • Isolated high speed clock and data links
