GENERAL DESCRIPTION

The ADA4433-1BCP-EBZ evaluation board makes it easy for
designers to quickly observe the performance of the ADA4433-1
video filter in real-world applications. Input signals are applied
through the SMA jacks (+IN, −IN), and outputs are taken from
SMA jacks (+OUT, −OUT). Power is applied through the red +VS
test point. Ground the black GND test point. The ADA4433-1
operates on a single-supply voltage ranging from 2.6 V to 3.6 V,
and draws approximately 14 mA.

The evaluation board is configured with an input termination
resistor (R1) of 75 Ω. Chose this resistor to provide the correct
termination or load for the input signal source. For example,
current-mode video digital-to-analog converter (DAC) outputs
that require a 300 Ω load resistance. In this case, replace R1 with a
300 Ω resistor.

The ADA4433-1 inputs can be driven by either a balanced or an
unbalanced source. For unbalanced signals, bias the unused input
(−IN) to approximately 0.5 V. For a 3.3 V supply, this can be achieved
by using the on-board voltage divider by setting R2 = 1.33 kΩ and

R3 = 7.5 kΩ. Populate the decoupling capacitor (C3) with 0.1 µF to
help eliminate noise.

By default, the ADA4433-1BCP-EBZ is configured for single-ended
input operation where the input signal is applied to SMA (+IN).
For a balanced input configuration, R4 provides placement for
the differential termination resistor.

The ADA4433-1BCP-EBZ evaluation board is configured to drive
a back terminated 150 Ω differential load. Series back-termination
resistors (37.5 Ω each) are installed on both outputs. These can
be changed to match the actual differential load impedance.

The ADA4433-1 can be powered down (disabled) by grounding
the green ENA test point at the top left of the evaluation board.
On the evaluation board, this pin is pulled up to +VS through
the 4.7 kΩ resistor (R7).

In normal operation, the short-to-battery output flag (STB) is
held at a logic low. During a short-to-battery fault condition (where
a voltage ranging from 5 V to 18 V is applied to either or both
outputs), the STB output voltage is driven to a logic high state. The
STB yellow test point (lower left side of the evaluation board) can
be used to monitor the short-to-battery output flag function.

Figure 1 shows the evaluation board, primary side and secondary
side. Figure 2 shows the evaluation board schematic. The printed
circuit board (PCB) layout pattern for the primary side and
secondary side are shown in Figure 3 and Figure 4.
