8 PHY CONTROL
8.1 Output Voltage Swing Control
The output swing of each transmitter can be independently set to one of a number of settings via the
SWING bits in the De-Emphasis and Swing Control Register, see Section 4.65.
Reducing the output amplitude decreases the current drawn in direct proportion to the reduction in swing,
thereby saving power.
