ADN4651

5 kV rms, 600 Mbps Dual Tx and Rx Channel LVDS Isolator

Manufactured by:

Product Details

The ADN4651 is a signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 600 Mbps with very 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 technology allows drop-in isolation of an LVDS signal chain.

Multiple channel configurations are offered, and the LVDS receivers on the ADN4651 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 regulator (LDO) 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 are available in a 20-lead, wide body SOIC package with 5 kV rms isolation or a 20-lead SSOP package with 3.75 kV rms isolation.

Applications

  • Analog front-end (AFE) isolation
  • Data plane isolation
  • Isolated high speed clock and data links
  • Isolated serial peripheral interface (SPI) over LVDS

Product Details

The EVAL-ADN4651EB1Z and EVAL-ADN4652EB1Z allow quick and easy evaluation of the ADN4651/ADN4652 low-voltage differential signalling (LVDS) isolator without the need for external components. The ADN4651/ADN4652 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. They are capable of running at data rates of up to 600 Mbps with very low jitter.


The evaluation board has separate ground and power planes for each side of the isolator. This separation enables the evaluation of the ADN4651/ADN4652 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 ADN4651/ADN4652. Using an on-chip LDO, 2.5 V can be provided from an external 3.3 V power supply.


Complete information about the ADN4651/ADN4652 is available in the ADN4650/ADN4651/ADN4652 data sheet, which should be consulted in conjunction with user guide UG-900 when using the evaluation boards.
