Analog Devices

The ADN4654/ADN4655/ADN46561are signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 1.1 Gbps with 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 integration allows drop-in isolation of an LVDS signal chain.The ADN4654/ADN4655/ADN4656 comprise multiple channel configurations, and the LVDS receivers on the ADN4655 and ADN4656 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 (LDO) regulator 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 come in a 20-lead, wide body SOIC_W package with 5 kV rms isolation or in a 20-lead SSOP package with 3.75 kV rms isolation.ApplicationsIsolated video and imaging dataAnalog front-end isolationData plane isolationIsolated high speed clock and data links1Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.

The ADN4661 is a single, CMOS, low voltage differential signaling (LVDS) line driver offering data rates of over 600 Mbps (300 MHz) and ultra-low power consumption. It features a flow-through pinout for easy PCB layout and separation of input and output signals.The device accepts low voltage TTL/CMOS logic signals and converts them to a differential current output of typically ±3.1 mA for driving a transmission medium such as a twisted-pair cable. The transmitted signal develops a differential voltage of typically ±355 mV across a termination resistor at the receiv-ing end, and this is converted back to a TTL/CMOS logic level by a line receiver.The ADN4661 and a companion LVDS receiver offer a new solution to high speed point-to-point data transmission, and a low power alternative to emitter-coupled logic (ECL) or positive emitter-coupled logic (PECL).ApplicationsBackplane data transmissionCable data transmissionClock distribution
