Frequency synthesizers have lots of other specs that you don't mention, such as jitter (phase noise), tuning speed, phase windup, ... > The PLL's I've looked at don't have the range, synthesizers > don't have the speed (500k Hz max.) The PLL only needs an octave of tuning range. Get the rest with a selectable number of binary dividers on the output. > Ideas??? For ideas, I'd go for maintenance manuals of commercial frequency synthesizers. Bob
