GENERAL DESCRIPTION

The ADN4650/ADN4651/ADN46521 are 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/ADN4652 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.
