hi this is hari,
please can anyone help me, i am using AD9834 DDS ic for generating sine,triangular and square waveforms upto 3.3MHz(meha) interface with ARM7(LPC2378) processor. i am successfully created sine, triangular waveforms. square waveform also generated correctly except 1.1Mhz ,2.2Mhz, 3.3Mhz.i am using FREQ0,Phase0. but waveform is not standard position. i have attached my square wavwform output in this mail. please can anyone help me create a exact square wave.
the control register, LSB Reg and MSB Reg values are
contorl REG - 0x2028
LSB REG - 63D7
MSB REG - 41C2
i am using 40mhz mclk. msb & lsb data's are 1.1mhz generated values
