Analog Devices: AD9106-EBZ Evaluation Board for AD9106 DAC and Waveform Generator

Kit Overview

The AD9106-EBZAD9106-EBZ evaluation board includes a PIC 18F455018F4550 processor programmed to function as a PC USB interface to the SPI port of the device. The AD9106AD9106 is a Quad Digital to Analog converter and Waveform Generator. And an AD9514 clock chip that takes in a 1440Mhz signal from the clock source and provides the CLKP/N input to the AD9106. The EVB runs from a single 5 volt supply.

The AD9106AD9106 Evaluation Board GUI software has a number of tabs. Each tab allows the user to view or manually program a subset of AD9106 registers and on-chip data RAM. The RAM tab lets the user download vectors to the RAM. The AD9106 evaluation board CD includes RAM vectors for use with example files described below where appropriate. There is a DAC tab for each of the four AD9106 DACs. The DAC tabs depict the waveform generation signal chain for each DAC. The Register Write Sequence tab is used to select and write register configuration files to the AD9106.

The AD9106AD9106 TxDAC and waveform generator is a high performance quad DAC integrating on-chip pattern memory for complex waveform generation with a direct digital synthesizer (DDS). The DDS is a 12-bit output, up to 180 MHz master clock sinewave generator with a 24-bit tuning word allowing 10.8 Hz/LSB frequency resolution. The DDS has a single frequency output for all four DACs and independent programmable phase shift outputs for each of the four DACs.

Key Applications: Medical instrumentation(Ultrasound transducer excitation), Portable instrumentation(Signal generators, arbitrary waveform generators).
