The AD59301 is a waveform generator with programmablefrequency sweep and output burst capability. Utilizingembedded digital processing that allows enhanced frequencycontrol, the device generates synthesized analog or digitalfrequency-stepped waveforms. Because frequency profilesare preprogrammed, continuous write cycles are eliminatedand thereby free up valuable DSP/microcontroller resources.Waveforms start from a known phase and are incrementedphase continuously, which allows phase shifts to be easilydetermined. Consuming only 8 mA, the AD5930 provides aconvenient low power solution to waveform generation.The AD5930 can be operated in a variety of modes. Incontinuous output mode, the device outputs the requiredfrequency for a defined length of time and then steps to thenext frequency. The length of time the device outputs aparticular frequency is either preprogrammed and the deviceincrements the frequency automatically, or, alternatively, isincremented externally via the CTRL pin. In burst mode, thedevice outputs its frequency for a length of time and thenreturns to midscale for a further predefined length of timebefore stepping to the next frequency. When the MSBOUT pinis enabled, a digital output is generated.(continued on Page 3)

(continued from Page 1)To program the device, the user enters the start frequency, theincrement step size, the number of increments to be made, andthe time interval that the part outputs each frequency. Thefrequency sweep profile is initiated, started, and executed bytoggling the CTRL pin.A number of different sweep profiles are offered. Frequencies canbe stepped in triangular-sweep mode, which continuously sweepsup and down through the frequency range. Alternatively, in saw-sweep mode, the frequency is swept up through the frequencyrange, but returns to the initial frequency before executing thesweep again. In addition, a single frequency or burst can begenerated without any sweep.The AD5930 is written to via a 3-wire serial interface, whichoperates at clock rates up to 40 MHz. The device operates witha power supply from 2.3 V to 5.5 V. Note that AVDD and DVDDare independent of each other and can be operated fromdifferent voltages. The AD5930 also has a standby function,which allows sections of the device that are not being usedto be powered down.The AD5930 is available in a 20-lead pb-free TSSOP package.
