Can I invert the transciever Tx polarity with a signal port when using the Stratix V device, Native PHY IP, 10G PCS?

Environment

  • Stratix® V GS FPGA
  • Stratix® V GT FPGA
  • Stratix® V GX FPGA
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

No, You cannot invert the transciever Tx polarity with a signal port when using the Stratix® V device, Native PHY IP, 10G PCS.

Resolution

To invert the transceiver Tx polarity of the Stratix V device Native PHY when using the 10G PCS you must use the Megawizard™ "Enable Tx Data Polarity Inversion" option.

This parameter will invert all Tx channels used in the IP variant as well as the PRBS Generator\'s data.
