AAIIGGHH!! Please, people, when you assist others with finding a part that does the trick they need done, include the part number that you are referring to, and, if possible, the name and phone number of the manufacturer and/or supplier. The part mentioned below would be of great value to me in an upcoming project, but alas, no part number or how-to-get-one info. > >Fox Ocillators makes a sealed Can device that can be programmed to generate >a frequency between about 450 kHz and 150 MHz. If you were to divide >this by 1024 or 1000 you would get the range you are looking for. > >The device is serially programmed but sweeping in frequency may not >be as smooth as you desire for filter purposes. > >Not I2C for the one I have also price about 20 .. 30 US$. > "DOS Computers manufactured by companies such as IBM, Compaq, Tandy, and millions of others are by far the most popular, with about 70 million machines in use wordwide. Macintosh fans, on the other hand, may note that cockroaches are far more numerous than humans, and that numbers alone do not denote a higher life form."
