Abstract
Transmission signals may generated based on three differential signals and transmitted along a channel. Each of the plurality of transmission signals may include a signal representative of each of the three differential signals. After receiving the transmission signals, the original three differential signals may be generated based on the transmission signals.
Claims20
An apparatus comprising:
- a preamplifier configured to generate a plurality of transmission signals for transmission over a plurality of conductors based on at least three differential signals, each transmission signal comprising a signal representative of each of the differential signals;
- and
- a read channel portion configured to receive the transmission signals over the conductors and generate the differential signals based on the transmission signals.
A method comprising:
- generating a plurality of transmission signals for transmission over a plurality of conductors based on at least three differential signals, each of the plurality of transmission signals comprising a signal representative of each of the at least three differential signals;
- receiving the transmission signals over the conductors;
- and
- generating the differential signals based on the transmission signals.

A system comprising:
- a preamplifier configured to:
- receive three differential signals,
- generate intermediate signals for each of the three differential signals, each intermediate signal defining a current proportional to the voltage difference of the differential signal, and
- selectively combine the intermediate signals to generate four transmission signals for transmission over four conductors, each of the plurality of transmission signals comprising a signal representative of each of the three differential signals.
