Quick Start Guide AD9707/AD9706/AD9705/AD9704‐EBZ EVALUATION SYSTEM AD9707 EVALUATION BOARD The AD9707, AD9706, AD9705 and AD9704 are single, high performance CMOS TxDACs. Their evaluation board includes a PIC 18F4550 processor programmed to function as an interface between the PC USB and the SPI port of the device. And an AD9512 clock chip that takes in an up to 175Mhz signal from the clock source and provides the CLK /CLK‐ input to the AD970x.

The content of on‐chip registers is shown in the “AD970x readback array” section of the GUI. Figure 3 displays the state of the registers at power up before the SPI software is run.

The SPI register access interface connects to the evaluation board through the PC USB as well. A 175MHz sinusoidal clock with an amplitude of 3dBm is used. DAC current outputs are converted from differential to single ended using an RF transformer on the EVB. The output at S4 is capable of driving 50 ohms. ©2010 Analog Devices, Inc. All rights reserved.
