SETTING UP THE EVALUATION BOARD
DC Power Supply
The AD9910 evaluation board has two power supply connectors
(four pins each): TB1 and TB2. TB1 powers the USB interface
circuitry, the digital I/O interface, and the digital core. TB2
powers the DAC and the clock input circuitry.
CONNECTORS
Table 2 shows the necessary connections and the appropriate
biasing voltage.

Device Clock Oscillator Options
The AD9910 architecture provides the user with three options
when providing an input signal to the part. The first option allows
the user to provide a high frequency input signal, connected to J1.
The second option allows the user to connect using a lower input
reference frequency, enabling the clock multiplier, and connects
through J1. The third option allows the user to connect a crystal
resonator on the backside of the board.
To enable the crystal mode, switch the jumper, W7, to the XTAL
mode. Remove C51 and 52. Place 0 (zero) Ω resistors at R4 and
R11 on the backside of the board. The crystal oscillates at 25 MHz.
Refer to the AD9910 data sheet for details on the maximum input
speeds and input sensitivities of these two inputs.
Device Communication Requirements
Two interface options are available on the evaluation board.

Analog Devices provides a GUI for the PC; it does not provide
control software for external controllers.
JUMPERS
Use the jumper settings listed in Table 3 to enable different
modes of communication.

Control
Jumper W1, Jumper W2, and Jumper W4 enable the USB
circuitry to control the AD9910. Jumper W3 controls the
EEPROM, used in starting up the USB circuitry. Jumper W5
and Jumper W6 control Signal SDO and Signal SDIO to and
from the AD9910.
USB 1.1/2.0
Header row (U5 and U9), which places the part under the
control of an external controller (such as a microprocessor,
FPGA, or DSP)
Settings
Set Jumper W1and Jumper W2 to enable. Set
Jumper W4 to enable. Place a jumper on W5, W6,
and W3.
Set Jumper W1and Jumper W2 to disable. Set
Jumper W4 to disable. Remove the jumper on
W5, W6, and W3.
