The ADN4651 is a signal isolated, low voltage differential signaling (LVDS) buffer that operates at up to 600 Mbps with very low jitter.
The devices integrate iCoupler technology, enhanced for high-speed operation, to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This allows drop-in isolation of an LVDS signal chain.
Multiple channel configurations are offered, and the LVDS receivers on ADN4651 include a fail-safe mechanism to ensure a logic 1 on the corresponding LVDS driver output when the inputs are floating, short circuit or not driven but terminated.
For high-speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5V supply. An integrated on-chip LDO can provide the required 2.5V from an external 3.3V power supply. The parts are fully specified over a wide industrial temperature range and are available in 20-lead wide-body SOIC package with 5kV rms isolation.
