GENERAL DESCRIPTION

The EVAL-ADN4620EBZ and EVAL-ADN4621EBZ allow quick and

easy evaluation of the ADN4620/ADN4621 low voltage differential

signaling (LVDS) isolators without the need for external components.

The ADN4620/ADN4621 employ the Analog Devices, Inc.,

iCoupler? technology to combine a 2-channel isolator with LVDS

receivers and drivers into a single, 20-lead SSOP package. The

ADN4620/ADN4621 are capable of running at data rates of up to

2.5 Gbps with low jitter.

The EVAL-ADN4620EBZ/EVAL-ADN4621EBZ have separate

ground and power planes for each side of the isolator, with individual

1.8 V power supplies required on each side of the ADN4620/

ADN4621. This separation enables the evaluation of the ADN4620/

ADN4621 with galvanic isolation between both sides of the devices.

An additional power supply providing 3.3 V is required on Side 1

(and also Side 2 for the ADN4621).

For full details on the ADN4620/ADN4621, see the ADN4620/

ADN4621 data sheet, which must be consulted in conjunction

with this user guide when using the EVAL-ADN4620EBZ or EVALADN4621EBZ.
