ADN4652 5 kV/3.75 kV rms, 600 Mbps Dual Channel LVDS Isolator
The ADN4652 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 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
