EVALUATION BOARD DESCRIPTION

This data sheet describes the evaluation board for the AD5932

programmable single-scan waveform generator. The evaluation

board interfaces to the USB port of a PC. It is possible to power

the entire board off the USB port. Software is available with the

EVAL-AD5932EB, allowing users to easily program the

AD5932.

The AD5932 evaluation board includes a 50 MHz oscillator that

provides the MCLK for the

AD5932. The user can remove this

oscillator, if required, and drive the

AD5932 with a different

clock oscillator or an external clock source via a subminiature

BNC connector.

AD5932 DEVICE DESCRIPTION

The AD5932 is a waveform generator that allows a user to

generate synthesized analog or digital frequency-stepped

waveforms. Because frequency profiles are preprogrammed,

continuous write cycles are eliminated, which frees up valuable

DSP/Controller resources. Waveforms start from a known

phase and increment phase continuously allowing phase shifts

to be easily determined. The part can be operated with clock

frequencies up to 50 MHz.

Complete specifications for the

AD5932 are available in the

AD5932 data sheet available from Analog Devices, Inc., and

should be consulted in conjunction with this data sheet when

using the evaluation board.

EVAL-AD5932EB HARDWARE DESCRIPTION POWER SUPPLIES The AD5932 device has two analog power supply inputs: AVDD (Analog VDD) and AGND (Analog GND). There are also two digital supplies on the part, DVDD (Digital VDD) and DGND (Digital GND). Both of these supplies are independent of each other and can be powered from 2.3 V to 5.5 V. As well as supplying the digital supply for the AD5932, DVDD is used to provide the supply for the 50 MHz oscillator and the ADG774 quad 2:1 mux.

EVAL-AD5932EB LINK OPTIONS The link options on the evaluation board should be set for the required operating setup before using the board. The functions of these links are described in Table 1. Table 1. Link Options Link No. LK1 Function This link selects the power supply source for the digital circuitry (DVDD). LK2 This link controls whether the serial interface of the AD5932 is being driven from a PC or being used in standalone mode. LK3 This link selects the MCLK source.

EVAL-AD5932EB EVALUATION BOARD SOFTWARE The AD5932EB evaluation kit is shipped with a CD-ROM that includes self-installing software. The PC is connected to the evaluation board using the supplied cable. The evaluation software should be installed before connecting the evaluation board to the PC’s USB port. This ensures that the evaluation board is correctly recognized when connected to the PC. The software is compatible with Windows® 2000 and Windows XP.

Now click Write to Part, which is the first communication with the board. This write programs the AD5932 registers. However, it is necessary to click Pulse CTRL Pin in order to start the frequency sweep.

EVAL-AD5932EB ORDERING GUIDE Model EVAL-AD5932EB Description Evaluation Board ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges.
