GENERAL DESCRIPTION

APPLICATIONS

The ADN4620/ADN4621¹are dual-channel, signal isolated, low

voltage differential signaling (LVDS) buffers that operate at up to

2.5 Gbps with very low jitter. The devices integrate Analog Devices,

► Analog front-end isolation

► Data plane isolation

► Isolated high speed clock and data links

► Multigigabit serialization/deserialization (SERDES)

► PCB-to-PCB optical replacement (for example, short reach fiber)

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 ADN4620/ADN4621 include a refresh mechanism to monitor

the input and output states and ensure that 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 isolator circuits rely on 1.8 V supplies, while 3.3 V supplies are

used for LVDS receivers to support the full common-mode range

with an input voltage range (input common mode plus differential

input voltage) of 0 V to 2.4 V per Table 2.

The devices are fully specified over a wide industrial temperature

range and are available in a compact SSOP package with 5.3

mm creepage (for reinforced insulation at ac mains voltages) or a

wide SOIC_IC package with 15.1 mm creepage (for high working

insulation voltages up to 1500 V peak, reinforced).
