Evaluation Board for Programmable Single-Scan Waveform Generator EVAL-AD5932EB Full-featured evaluation board for the AD5932 USB cable for PC connection Can be powered entirely from USB port Various linking options PC software for control of AD5932 On-board patchwork area 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/uController 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.

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 V to 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. There are two options available to power the AD5932 evaluation board: • The USB port of a computer • A power supply The default option for powering the board is from the USB port LK1 and LK8 are in Position B . Alternatively, 2-pin terminal blocks are available to the user for use with an external power supply. EVAL-AD5932EB The 5 V from the USB port is regulated to V, which provides power for the CY7C68013 USB controller and related USB circuitry. The USB port also provides the GND connections for the board. When LK1 is in Position B, DVDD is supplied with V from the regulator. When LK8 is in Position B, AVDD is powered from DVDD through ferrite bead L1 600 Ω 100 MHz . When LK1 and LK8 are in Position A, the terminal blocks are used to provide power to the board. Note that if you need to operate the part at a different supply than up to V, the terminal blocks should be used. In addition, to abide by the maximum ratings of the AD5932, the board should be used as a standalone board if operating at a voltage less than 3 V. Therefore, SCLK, SDATA, FSYNC, CTRL, INTERRUPT, and STANDBY must be externally supplied by the user. DGND and AGND are connected under the AD5932. Therefore, it is recommended not to connect AGND and DGND elsewhere in the system. AVDD and DVDD are decoupled to the relevant ground plane using a 10 uF tantalum capacitor and a uF ceramic capacitor at their source and again at the AD5932.
