I work at an electronics contract manufacturimg facility. We do work for

X1, or an IC1. Why do they do this? Is there a standard used to label IC's
in a schematic? Just curious why this is.

The standard reference designator for integrated circuits is "U" -
anything else is wrong! ( IMHO :-) )

And what does U stand for ? Probably the stupidest choice ever aside from Q.


Sigh. Do ANY of your neurons work? It was another available letter,
and used to identify the 'Unique' integrated circuits.
