The biggest advantage of programmable oscillator compared to fixed frequency oscillator is the lead-time. We can produce blank products without any frequency in advance. The second advantage of programmable oscillator is that it can do high frequencies. The third advantage is that it can do any special frequency, which allows designers to flexibly choose any frequency, including frequencies that are not easily available on the market. You can choose a variety of voltages: available in 1.8V, 2.5V, 3.3V providing jitter performance as low as 0.15ps for all applications.
