Up to 4x faster data throughput than competing products at 600Mbps
Ultra-low jitter performance at 70ps, with a maximum propagation delay of only 4.5ns

Analog Devices (ADI) has launched a series of low-voltage differential signal (LVDS) digital isolators designed to improve performance, reliability, and reduce power consumption in industrial instrumentation and programmable logic controller (PLC) applications.

Previously, supporting LVDS signal isolation in industrial instrumentation and PLC applications required interface redesign. Leveraging ADI's award-winning iCoupler® digital isolation technology, the ADN465x series provides proven galvanic isolation in a single package for safety and reliability, while delivering a data throughput rate of 600 Mbps (up to 4x faster than competing products) and ultra-low jitter performance at 70 ps with a maximum propagation delay of only 4.5 ns. The ADN465x devices enable direct isolation of high-speed serial LVDS signals without the need for deserialization, unlike previous implementations. These products provide a high-performance, LVDS-compatible, commercially available solution, saving design resources and time.

Data generated from an increasing number of sensors in industrial PLC backplanes is distributed among processing nodes for enhanced control while maintaining robustness against system-dependent interference. New LVDS digital isolators that support ultra-low jitter of 70 ps, full compliance with the TIA/EIA-644-A standard, enhanced isolation with surge protection tested to 10 kVpk, and the ability to withstand rated voltages up to 5 kVrms enable further I/O integration even when passing meters of cable at high signal rates.

Providing high-performance commercial solutions compatible with LVDS
Save design resources and time

Real-time analysis of grid supply is crucial, as the density of server farms continues to increase, forcing power grids to expand to support demand. Smart power quality analyzers capable of real-time analysis require high-speed, high-precision data. The ADN465x LVDS digital isolators support data rates up to 600 Mbps and a 300 MHz clock, enabling isolation of precision converters with LVDS interfaces.

Source-synchronous interfaces are supported with channel-to-channel skew as low as 200 ps. Ultra-low additive phase jitter of 380 fs allows isolation of the ADC sampling clock while maintaining low aperture jitter for full ADC performance and resolution.
