GENERAL DESCRIPTION
The ADN4612 evaluation board user guide describes the setup
and general usage of the ADN4612 evaluation board. Included
in this document is a quick start guide, hardware configuration
instructions, and software installation instructions.
The ADN4612 evaluation board provides access to all 12
differential input ports and 12 differential output ports of the
ADN4612 via top launch SMA connectors. Each input and output
pair is ac-coupled using a 0.1 μF capacitor.
The evaluation board example (see Figure 1) is shown fully
populated with SMA connectors. The board is shipped with
only eight installed SMA connectors. The SMA connectors can
be moved to any of the 48 locations on the board by unscrewing
and then reattaching the connectors to the desired locations.
The customer can purchase an additional 40 SMA connectors
from several different sources and attach the connectors for a
fully populated board. The Bill of Materials section in this user
guide provides the SMA connector part number, which is
Molex 73251-1851 or equivalent.
All microstrip (top layer) transmission lines use an RoHs-
compliant, Megtron-6 dielectric. The differential transmission
line pairs are 10 mil wide with 7.5 mil spacing and are designed to
have a differential characteristic impedance of 100 Ω. The stripline
(middle layers) transmission lines are RoHs-compliant, FR-4
material.

QUICK START GUIDE
This section provides a quick start procedure for using the
ADN4612 on the evaluation board. The following procedure
describes how to set the default settings:
1. Insert the 12 V adapter terminal into connector P58.
2. Set the power switch (S3) to the on position.
3. Connect the provided USB cable from the PC to the USB
connector on the evaluation board (P56).
4. Connect IPx (positive) and INx (negative) to a pattern
generator to receive a pseudorandom binary sequence
(PRBS) signal. It is important to use a pair of matched
length, 50 Ω cables.
5. Connect OPx and ONx to an oscilloscope using a pair of
matched length, 50 Ω cables.
6. Apply a data pattern signal (any rate up to 11.3 Gbps) to
the ADN4612. A signal with an amplitude of 800 mV p-p
differential is a good signal for an initial test.
7. Extract the contents of the compressed ADN4612
Evaluation Software .zip file to a folder on the PC.
8. Double-click ADN4612_0vX.exe to run the ADN4612
evaluation software.
9. Use the software provided to control the ADN4612. Refer
to the Software Overview section for details on how to
configure a channel for evaluation.
The graphical user interface (GUI) resets the device and sets the
receiver, crosspoint switch core, and transmitter to a default
configuration. The user can click the RESET DEVICE button to
ensure that the ADN4612 is in the correct default state and matches
the user interface. The reset operation may take several seconds to
complete and can be monitored via the progress bar.

EVALUATION BOARD HARDWARE
POWER SUPPLIES
The ADN4612 consists of core, input/output, and digital logic
supplies. All supplies are referenced to VEE (typically 0 V). The
evaluation board supply voltages are listed in Table 1.
A 12 V/5 A (60 Hz) power adapter (provided with the evaluation
kit) supplies power to the ADN4612 evaluation board. An on/off
switch enables or disables power to the board. A switch regulator
provides 12 V to 5 V dc-to-dc conversion. Analog Devices, Inc.,
linear dropout regulators generate the correct VCC25, VCC18,
VDD18, VTTI, and VTTO supply voltages for the ADN4612.
INPUT SIGNALS
High Speed Differential Serial Inputs (INx/IPx)
The ADN4612 receives a differential or single-ended signal
through the top launch, screw-fit SMA connectors (Molex,
Model 73251-1851), labeled INx and IPx.
The SMA connectors can move to any connector placement
location on the evaluation board. A differential input signal level
of 800 mV p-p differential is suggested for initial investigation.
With ac signal coupling, ADN4612 supports not only current
mode logic (CML), but also low voltage differential signaling
(LVDS) and low voltage positive referenced emitter coupler
logic (LVPECL). Ceramic capacitors provide the ac coupling
path to the signal input. To match with the 50 Ω transmission
line, the ADN4612 has on-chip, 50 Ω termination resistors at
the input pads.
OUTPUT SIGNALS
High Speed Differential Serial Outputs (OPx/ONx)
The CML outputs are ac-coupled to the SMA connectors,
labeled OPx and ONx, through ceramic capacitors.
