Evaluation Board For Single Supply 12-bit 500 Ksps Adc


Posted on Feb 6, 2014

This data sheet describes the evaluation board for the AD9834 direct digital synthesizer (DDS). The AD9834 is a numerically controlled Oscillator using a phase accumulator, a sine look-up table, and a 10-bit DAC The AD9834 CAN be operated with Clock frequencies up to 75 MHz. Both phase modulation and frequency modulation CAN be perfor

med with the AD9834. Complete specifications for the AD9834 are available in the AD9834 data sheet and should be consulted in conjunction with this data sheet when using the evaluation board. The evaluation board Interfaces to the parallel port of a PC. Software is available with the evaluation board that allows the user to easily program the AD9834. The AD9834 evaluation board includes a 75 MHz Oscillator that provides the MCLK for the AD9834. The user CAN remove this Oscillator if required, and drive the AD9834 with a different Clock Oscillator or an external Clock source via a BNC connector. A digital Buffer is also on the board so that the signals from the edge connector are buffered.
