Can I use LTC1799 as below for reduce Jitter?
Why is Rset minimum 5k Ohm at ELECTRICAL CHARACTERISTICS?
This will not work for multiple reasons. First, the minimum Rset resistor is 5k. Smaller than 5k will result in internal currents running too high and saturating some internal nodes. Second, this would require the internal VCO to operate at 41.7MHz well beyond its 33MHz limit. Please note that these silicon oscillator parts are not particularly low jitter. They are fine for clocking switching regulators, switched capacitor filters and many digital systems, but they are not really even close to the jitter obtainable from a standard crystal oscillator. You could consider trying an LTC6905 running at divide by 4 giving 41.7MHz and then following this with discreate digital divide by 10 circuit. This would have lower jitter, but still not close to a crystal oscillator.
