Product Details

The ADN46541 is a signal isolated, low voltage differential signaling (LVDS) buffer that operates 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. iCoupler technology allows drop-in isolation of an LVDS signal chain.

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 device is fully specified over a wide industrial temperature range and is available in a 20-lead, wide body SOIC_W package with 5 kV rms isolation.

Applications

  • Isolated video and imaging data
  • Analog front-end isolation
  • Data plane isolation
  • Isolated high speed clock and data links
