GENERAL DESCRIPTION
The EVAL-ADN469xEHDEBZ allows quick and easy evaluation
of half-duplex M-LVDS transceivers (ADN4690E, ADN4691E,
ADN4694E, and ADN4696E). The evaluation board allows all of
the input and output functions to be exercised without the need
for external components. Screw terminal blocks provide convenient
connections for power and ground, with SMB jack connectors
for high speed logic and M-LVDS bus signals.
The evaluation board has an 8-lead SOIC footprint for a halfduplex M-LVDS transceiver from the ADN469xE family (see
Table 1).

EVALUATION BOARD CONFIGURATION
SETTING UP THE EVALUATION BOARD
are connected in Position B to enable the receiver and disable
the driver. Oscilloscope probes are attached to RO, A, and B.
The EVAL-ADN469xEHDEBZ allows the ADN4690E/
ADN4691E/ADN4694E/ADN4696E to be quickly and easily
evaluated. The evaluation board allows all of the input and
output functions to be exercised without the need for external
components. Jumper configurations are shown in Table 2.
EVALUATION WITH APPLICATIONS
Two EVAL-ADN469xEHDEBZ boards can be connected
together in a point-to-point configuration as shown in Figure 4.
In order to allow part evaluation with a load equivalent to a
parallel-terminated bus, the boards have been fitted with 50 Ω
termination resistors. For the point-to-point configuration in
Figure 4, these should be replaced with resistors of 100 Ω.
The board is powered by connecting a 3.3 V power supply
to the screw terminals for VCC and GND. Supply current is
typically 16 mA with both driver and receiver enabled, or 1 mA
with both disabled. A 10 µF decoupling capacitor, C1, is fitted
at the connector between VCC and GND. The VCC pin of the
ADN469xE is fitted with a decoupling capacitor of 100 nF.
A signal generator is connected onto one board’s DI input. This
boards A and B outputs are respectively connected to the
second board’s A and B inputs.
An example evaluation of the ADN4690E/ADN4691E/
ADN4694E/ADN4696E driver is shown in Figure 2. A
signal generator is connected to DI with an input signal of
50 MHz (ADN4690E/ADN4694E) or 100 MHz (ADN4691E/
ADN4696E), with a 50% duty cycle and swing of between 0 V
and 3.3 V. Jumpers LK1 and LK2 are connected in Position A to
disable the receiver and enable the driver. Oscilloscope probes
are connected to DI, A, and B.
Connecting probes to DI on the first board, and A, B, and RO
on the second, the propagation of the input signal across the
bus and to the receiver output of the second board can be
observed and evaluated.
Alternatively, the EVAL-ADN469xEHDEBZ can be connected
to an existing bus and a control board as shown in Figure 5 in
order to test the performance in the application. In this case,
both termination resistors should be removed, as well as the
jumpers on LK1 and LK2. Control signals should be connected
to RO, RE, DE, and DI.
Similarly, an evaluation of the ADN4690E/ADN4691E/
ADN4694E/ADN4696E receiver is shown in Figure 3. A signal
generator capable of applying a differential input signal is
connected to J5 and J6, with the input swing between 1 V and
1.2 V (J6 input the inverse of J5 input). Jumpers LK1 and LK2
