2.9.2.13. TX Polarity Inversion
The positive and negative signals of a serial differential link might accidentally be
swapped during board layout. Solutions such as a board respin or major updates to
the PLD logic can be expensive. The transmitter polarity inversion feature is provided
to correct this situation.
Transmitter polarity inversion can be enabled in low latency, basic, and basic rate
match modes.
To enable TX polarity inversion, select the Enable tx_polinv port option in Platform
Designer (Standard). It can also be dynamically controlled with dynamic
reconfiguration.
This mode adds tx_polinv. If there is more than one channel in the design,
tx_polinv is a bus with each bit corresponding to a channel. As long as tx_polinv
is asserted, the TX data transmitted has a reverse polarity.
