SY89307V Evaluation Board
General Description
The SY89307V evaluation board is designed for
convenient setup and quick evaluation of the
SY89307V. The boards are optimized to interface
directly to a 50 oscilloscope.
The default evaluation board I/O configuration is AC-
coupled. For applications that require a DC-coupled
configuration, step-by-step instructions for modifying
the board are included.
Data sheets and support documentation can be found
on Micrel’s web site at www.micrel.com.

Evaluation Board Description
The SY89307V evaluation board can be configured
for either AC-coupled or DC-coupled operation.
The default configuration for the boards is AC-
coupled inputs and AC-coupled outputs. The choice
between two configurations offers the user flexibility in
selecting the board that is right for his particular
application.
AC-Coupled Evaluation Board
The AC-coupled configuration is suited to most
customer applications and is preferred by the majority
of users because of its ease-of-use. It requires only a
single power supply of either 3.3V +10% or 5.0V
+10% and offers the most flexibility in interfacing to a
variety of signal sources.
The DC-bias levels and AC-coupling capacitors are
supplied on-board for each input, making it
unnecessary to vary the offset voltage or change any
components on the board as the power supply
voltage varies. The user needs only to supply a
minimum input voltage swing and the bias voltage will
automatically adjust the input to the correct level as
the power supply voltage varies.
DC-Coupled Evaluation Board
For DC-coupled operation, the board can be modified
to use two power supplies in a “split-supply
configuration”. Split-supply is an easy method to
interface to a 50 (to ground) scope. Therefore, a
3.3V supply will be split into +2V and -1.3V, and a
2.5V supply will be split into +2V and -0.5V. The +2V
offset in this two-power supply configuration then
provides the correct terminations for the device by
setting the Ground potential on the board to be
exactly 2 volts below the V
CC
supply. The V
EE
voltage
is then set to –1.3V for 3.3V to ensure proper V
CC
to
V
EE
voltage difference. .
Step-by-step instructions for modifying an AC-coupled
evaluation board for DC-coupled operation are
supplied in the “Modifying your AC-Coupled Board for
DC-Coupled Operation” section
