The following table describes TX Configurable debug ports for UDHSDI GT:
Signal | I/O | Description |
---|---|---|
gt_txpmareset_in
|
I |
This port is used to reset the TX PMA inside the GT transceiver. It is driven High and then deasserted to start the TX PMA reset process. In sequential mode, activating this port resets both the TX PMA and the TX PCS. |
gt_txpcsreset_in
|
I | This port is used to reset the TX PCS. It is driven High and then deasserted to start the PCS reset process. In sequential mode, activating this port only resets the TX PCS. |
gt_txdiffctrl_in
|
I | Driver Swing Control. The default is user-specified. All listed values
are in mVPPD. Note: The peak-to-peak differential
voltage is defined when TXPOSTCURSOR = 5'b00000 and TXPRECURSOR
=5'b00000.
For more information on pre-cursor and post-cursor driver ports, refer to UltraScale Architecture GTH Transceivers User Guide (UG576). |
gt_txpostcursor_in
|
I | Transmitter post-cursor TX pre-emphasis control. The default is
user-specified. All listed values (dB) are typical. Note: The TXPOSTCURSOR values are defined
when the TXPRECURSOR =5'b00000.
|
gt_txprecursor_in
|
I | Transmitter pre-cursor TX pre-emphasis control. The default is
user-specified. All listed values (dB) are typical. Note: The TXPRECURSOR values are defined
when the TXPOSTCURSOR =5'b00000.
