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