General Description
The SY69753AL and SY69754AL evaluation boards
are designed for convenient setup and quick
evaluation of the SY69753AL or SY69754AL. It
allows evaluation of the part over the full voltage-
range without requiring any modifications to the
board.
The evaluation board standard configuration is AC-
coupled for direct interface to a standard 50Ω-
compatible oscilloscope. For applications that require
a DC-coupled configuration, step-by-step instructions
for modifying the board are included.
Features
• LVPECL outputs
• Single +3.3V power supply
• AC-coupled configuration for ease-of-use
• I/O interface includes on-board termination
• Fully assembled and tested
• Reconfigurable for DC-coupled operation

Evaluation Board Description
The SY69753AL and SY69754AL share a common
evaluation board. The individual evaluation boards
are labeled to identify the specific device and the
configuration, either AC- or DC-coupled configuration,
for that board.
The default configuration for the boards is the AC-
coupled configuration and all boards are shipped with
this configuration. 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 +3.3V +10% and offers the
most flexibility in interfacing to a variety of signal
sources.
The 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.
SY69753AL/SY69754AL DC-Coupled Boards
For DC-coupled operation, the boards can be
modified to use two power supplies in a "split-supply
configuration". The term split-supply simply means
the +3.3V supply is split into a +2V and -1.3V power
supply configuration. This effectively offsets the board
by +2V. 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 so the device power
pins still see a full 3.3V potential between V
CC
and
V
EE
.
Step-by-step instructions for modifying an AC-coupled
evaluation board for DC-coupled operation are
supplied in the sub-section "Modifying your AC-
Coupled Board for DC-Coupled Operation."
