AD9834CRUZ Datasheet PDF - ADI

●The AD9834CRUZ is a 75MHz low power DDS Device, capable of producing high performance sine and triangular outputs. It also has an on-board comparator that allows a square wave to be produced for clock generation. Consuming only 20mW of power at 3V makes the AD9834 an ideal candidate for power-sensitive applications. Capability for phase modulation and frequency modulation is provided. This frequency register has 28 bits, with a 75MHz clock rate, resolution of 0.28Hz can be achieved. Similarly, with a 1MHz clock rate, this can be tuned to 0.004Hz resolution. Frequency and phase modulation are affected by loading registers through the serial interface and toggling the registers using software or the FSELECT pin and PSELECT pin, respectively. This is written to using a 3-wire serial interface. This serial interface operates at clock rates up to 40MHz and is compatible with DSP and microcontroller standards.
