AD5930:  Programmable Frequency Sweep and Output Burst Waveform Generator

Product Details


The AD5930 is a waveform generator with programmable frequency sweep and output burst capability. Utilizing embedded digital processing allowing enhanced frequency control the device generates synthesized analog or digital frequency-stepped waveforms. Because frequency profiles are preprogrammed continuous write cycles are eliminated, thereby freeing up valuable DSP/µController resources. Waveforms start from a known phase and are incremented phase continuously allowing phase shifts to be easily determined.

The AD5930 can be operated in three modes. In continuous output mode the device outputs the required frequency for a defined length of time and then steps to the next frequency. The length of time the device outputs a particular frequency can be either preprogrammed and the device increments the frequency automatically or alternatively can be incremented externally via the CTRL pin. In Burst mode, the device outputs it’s frequency for a length of time and then returns to midscale for a further predefined length of time before stepping to the next frequency. In MSB mode a digital output is generated.

To program the device, the user enters the start frequency, the increment step size, the number of increments to be made and the time interval the part stays at each frequency. The frequency profile can be initiated by toggling the CTRL pin.

A number of different sweep profiles are offered. Frequencies can be stepped in triangular-sweep mode continuously sweeping up and down through the frequency range or in saw-sweep mode sweeping up but returning to the initial frequency before initiating the sweep again. In addition a single frequency or burst can generate without any sweep.

The AD5930 is written to via a 3-wire serial interface, which operates at clock rates up to 40 MHz. The device operates with a power supply from 2.3 V to 5.5 V and has a standby function which allows sections of the device that are not being used to be powered down.

The AD5930 is available in a 20-lead TSSOP package.

Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
