Hell, there are literally hundreds of PLL chips, lots of them better at various things than the 4046. I did not suggest that the 4046/7046/9046 is the best PLL for any particular purpose (and I did say I rarely use them). My points were just (i) that the 4046 doesn't perform as terribly as a lot of people seem to think if you know a few easy tricks, and (ii) that the 9046 is better on all counts without the need for such tricks.
It seems that lots of people like the 4046 series chips (including the 7046 and 9046), partly due to familiarity, partly because there are thousands of published circuits that use them and not everybody wants to completely redesign circuits that are already known to work, and certainly because they are dirt cheap (unlike the fancier Analog Devices parts, some of which are quite pricey). I thought these folks might like to know how to optimize performance with the 4046/7046/9046 series, and to be reminded about the design tools available for them.
