GENERAL DESCRIPTION

The ADN46241 is a quad-channel, signal isolated, low voltage

differential signaling (LVDS) buffer that operates at up to 2.5 Gbps

with very low jitter. The device integrates Analog Devices, Inc.,

iCoupler? technology, enhanced for high speed operation to provide

drop-in galvanic isolation of LVDS signal chains. AC coupling

and/or level shifting to the LVDS receivers and from the LVDS

drivers allows isolation of other high speed signals such as current

mode logic (CML).

The ADN4624 includes a refresh mechanism to monitor the input

and output states and ensure they remain the same in the absence

of data transitions (for example, at power-on).

For lower power consumption and high speed operation with low

jitter, the LVDS and isolator circuits rely on 1.8 V supplies. The

ADN4624 is fully specified over a wide industrial temperature range

and is available in a 28-lead, wide-body, finer pitch SOIC_W_FP

package with 8.3 mm creepage and clearance (for 5.7 kV rms or 8

kVPEAK surge and impulse voltages and reinforced insulation at ac

mains voltages) or 6 mm × 6 mm LFCSP package with 1.27 mm

creepage and clearance (for basic/functional isolation).
