I'm looking for a clock synthesizer IC that can drive my vintage 5V NMOS CPU in the range of 5 - 50MHz. The granularity would preferably be in the range of 100kHz or less. All I can find when searching the net are contemporary devices that have their lowest frequencies too high, and their output levels too low.
Any suggestions to current or legacy chips that could meet my demands are most welcome. I could even accept a complete circuit built from a small number components (due to restricted PCB estate), as an answer.
