Are the transmit/receive circuits really that complicated?

Actually, I had thought that this is presicely where we are supposedly
heading with all this SATA and PCI-X stuff.  It makes sense though when you
realise that a significant cost in IC fabrication[1] is the packaging, which
is basically proportional to the number of pins it has[2].

[1] I'm talking end-product fabrication, not design/testing.
[2] except with very large chips, where the cost of dud chips resulting from
flaws in the silicon far outweighs the packaging costs.
