GENERAL DESCRIPTION
The ADN4622/ADN46241 are quad-channel, signal isolated, lowvoltage
differential signaling (LVDS) buffers that operate at up to
2.5 Gbps with very low jitter. The devices integrate 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 ADN4622/ADN4624 include a refresh mechanism to monitor
the input and output states and ensure they remain the same in
the absence of data transitions. For lower power consumption and
high-speed operation with low jitter, the LVDS and isolator circuits
rely on 1.8 V supplies. The ADN4622/ADN4624 are fully specified
over a wide industrial temperature range and are 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).
