产品详情

This user guide takes users through the setup and use of the AD9951/PCBZ-SDP-K1 evaluation board. The AD9951 is a direct digital synthesizer (DDS) that uses advanced technology, coupled with an internal high-speed, high-performance digital-to-analog converter (DAC) to form a complete, digitally programmable, high-frequency synthesizer capable of generating a frequency agile, analog output, sinusoidal waveform at up to 160MHz with many user-programmable functions.

The Analog Devices, ACE Software provides a graphical user interface (GUI) for simple communication with the AD9951. The AD9951/PCBZ-SDP-K1 requires the use of an SDP-K1 controller board, which is not supplied with the evaluation board kit and must be purchased separately. The SDP-K1 controller board, along with the use of the ACE Software, allows users the ability to program the software.

The AD9951/PCBZ-SDP-K1 uses the same evaluation board as the AD9954/PCBZ-SDP-K1 with the only difference being the device on the board.

For full details on the AD9951, see the AD9951 data sheet, which must be consulted in conjunction with this user guide when using the AD9951/PCBZ-SDP-K1.
