The AD9858/PCBZ is an evaluation board for evaluating the performance of AD9858. The AD9858 is a 1GHz direct digital synthesiser (DDS) featuring a 10bit DAC, an RF mixer and onchip PLL synthesis blocks. Used in conjunction, the various components of the AD9858 allow the user to construct translation loops (also known as offset loops), fractional divider loops, traditional integer-N PLL loops, as well as frequency synthesis directly from the DDS. The DAC output evaluation board was designed to allow the user full control over some or all of the functional blocks of the AD9858. Each of the functional blocks has its inputs and outputs brought on and off board separately. Users can configure and connect the DDS block, the PLL block, and the mixer block in whatever fashion they wish, bounded by the parametric limitations of the device.
