Me too, but I think the reality is that I don't think there is such a 
thing except maybe in some early ASICs. Today FPGAs rule that world. The 
benefit is naturally that functional updates can come cheaply if 
provision is made for remove firmware updates.:)

The closest I can come up with is maybe WWV receiver chips. But that is 
IRIG-H and not IRIG-B.

The only reasons for heading down the audio ADC/DAC route over 8-bit is 
dynamic range and cost. It makes sense for IRIG-B102 signals.

Cheers,
Magnus
