Features 1 AD9834 is a 75 MHz low power DDS device capable of producing high performance sine and triangular outputs Also integrates its on chip comparator support the generation of square wave for clock generation When the supply voltage is 3V the power consumption of only 20mW very suitable for power sensitive applications 2 AD9834 provides a phase modulation and frequency modulation function Frequency register 28bit clock rate of 75MHz can achieve a resolution of 0 28 Hz Similarly when the clock rate is 1 MHz AD9834 can achieve a resolution of 0 004Hz Affect the frequency and phase modulation method is through the serial interface to load the register then register by software or FSELECT PSELECT pin switches Device 3 AD9834 via a three wire serial interface to write data The serial interface that operates at clock rates up to 40MHz and is compatible with digital signal processing and micro controller standards The device is 2 3V to 5 5V power supply Analog and digital sections are independent you can use different power supply for example AVDD can be 5V and DVDD can be 3V 4 AD9834 has a control pin Sleep SLEEP to support power down mode control from the outside No part of the device may shut off to minimize power consumption For example when generating a clock output can be turned off DAC The device uses a 20 pin TSSOP package 5 It is used for frequency excitation waveform generation frequency phase tuning and modulation low power RF c
