Hi

The one area that the chips have not quite yet taken over is the whole “software defined 
loop” or digital PLL. A GPSDO is one example of this, there are a number of other odd 
little niche areas they show up. 

Indeed, it’s been maybe 20 years since I put a non-software PLL in a product and it was not
done entirely in an IC.
