Re: analog driver

2B1Q is a bidirectional signaling scheme (a "line code") used on telephone
lines in which 2 binary bits are encoded in a single "quaternary" symbol,
containing 4 amplitude levels. This line code is used to limit the
bandwidth, thus reducing crosstalk problems inside cable bundles.
