I looked for this too. The data for the F84A doesn't give RC
vs freq either apart from recommended limits of 5k and 100k
with 20pF. The 628 data shows only 10kHz to 8Mhz range
and as far as I can see no recommended RC values for that
range. Unless someone knows better, it looks like an
incomplete manual and something you/I/we will have to find
out for ourselves by measurement
