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.
