Programmable Frequency Sweep and Output Burst Waveform Generator

Analog Devices 

Data Sheet

GENERAL DESCRIPTION

(continued from Page 1)

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 that the part outputs each frequency. The

frequency sweep profile is initiated, started, and executed by

toggling the CTRL pin.

A number of different sweep profiles are offered. Frequencies can

be stepped in triangular-sweep mode, which continuously sweeps

up and down through the frequency range. Alternatively, in saw-

sweep mode, the frequency is swept up through the frequency

range, but returns to the initial frequency before executing the

AD5930

sweep again. In addition, a single frequency or burst can be

generated 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. Note that AVDD and DVDD

are independent of each other and can be operated from

different voltages. The AD5930 also 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 pb-free TSSOP package.
