Groovy Posted April 29, 2004 Report Share Posted April 29, 2004 Hello everyone...i was actually supposed to be doing another project..but it didnt go as planned. so now im doingA stand alone sine wave generator using Atmel chipIt requires to run at frequency of at least 25kHz, but the harmonic distortion is not critical and may be as high as 3%.Preliminary Specifications(i) The device will operate from a dual supply of nominally 12V, onboard power regulation will be used where required.(ii) The microcontroller used will be the Atmel AT90S2313 employing a 4MHz resonator as the clock source.(iii) The output voltage required is 0dBm into 600 Ohms the output impedance is of course 600 Ohms.(iv) Some means of adjusting the frequency will be provided. (v) PCB size will not exceed 80mm by 50mm.So if anyone has any ideas..please let me know..me only a beginne :Dr...so any websites to learn would be great as well..thanx alot.thanx to everyone...
