INTRODUCTION
The AD9148 Evaluation Board connects to a DPG2 to allow for quick evaluation of the AD9148. Control of the SPI port in the AD9148 is
available through USB with accompanying PC software.

To ease the subsystem evaluation, a clock distribution chip (AD9516) and a quadrature modulator are also designed into this evaluation
board.
board.
SOFTWARE
The AD9148 Evaluation board is designed to receive data from a Data Patten Generator 2 (DPG2). The DAC Software Suite, plus the
AD9148 Update, is required for evaluation. The DAC Software Suite is included on the Evaluation Board CD, or can be downloaded from
the DPG web site at http://www.analog.com/dpg. This will install DPGDownloader (for loading vectors into the DPG2) and the AD9148
SPI application.

HARDWARE SETUP
Connect a +5V DC power supply to the banana jacks (P5 and P6). A clock source should be connected to the SMA jack labeled J1
(CLKIN). The AD9516 buffers this clock and distributes clock signals with proper frequencies to the AD9148 and the DPG2. In order to
monitor the desired outputs, a spectrum analyzer should be connected:

monitor the desired outputs, a spectrum analyzer should be connected:
-
To the SMA jack labeled J3 (OUT1) for DAC1 output or J8 (OUT2), J16 (OUT3), J9 (OUT4) for DAC2, DAC3, DAC4 output
respectively if the evaluation board you ordered is AD9148-EBZ.

DPG2 connects through connector P1 and P2 on the left edge of the evaluation board, and the USB cable should be connected to the mini
USB connector labeled XP2 USB SPI on the top side of the board. Note that the PC software needs to be installed before connecting the
USB cable to your computer.

JUMPER CONFIGURATIONS
There are 6 (on the AD9148-EBZ) and 7 (on the AD9148-M5372/5-EBZ) pin jumpers and 2 solder jumpers on the evaluation board.
The pin jumpers are corresponding to the 6 supplies, i.e., AVDD3.3, DVDD1.8, CVDD1.8 and etc, on the board. They serve as ‘switches’
that determine if the LDOs on board or external supplies are used for each individual supply. Most of the pin jumpers, except JP1, are 2
