Not sure how calculated this - the PN chart for PL133-37 shows output jitter barely lifting off the input jitter trace. LT do not say what their input jitter is.
Additive jitter for 100MHz 12kHz-20MHz is 80fs for PLL133-37 and 90fs for LTC6957 at more than 10 times lower price. I would trust LT more but all this is still armchair engineering. The only way to know is stick it on the board and check. Note that PLL133-37 is AC coupled internally so not suitable for short sharp spikes or low frequencies.
