12.1. F-Tile DisplayPort PHY FPGA IP Parameters

The configuration GUI has three tabs for PHY configuration. When you select a PHY configuration in the IP tab, the GUI dynamically displays or hides the Receiver and Transmitter tabs.
Table 251.  F-Tile DisplayPort PHY IP Parameters
Parameter Values Default Description
Phy configuration

Tx

Rx

Rx Selects the PHY configuration as either Rx or Tx.
Lanes

1, 2, or 4

4

The DisplayPort protocol supports 1,2 or 4 lanes. This configuration allocates 1,2 or 4 transceiver channels and adjusts the interface width between the PHY and protocol IP.

Ensure the PHY and protocol core lane settings are the same as mismatches cause malfunctions.

You cannot automatically detect this issue in your design.

Maximum Link Rate
  • RBR 1.62 Gbps
  • HBR1 2.7 Gbps
  • HBR2 5.4 Gbps
  • HBR3 8.1 Gbps
  • UHBR10 10Gbps
  • UHBR13 13.5 Gbps
  • UHBR20 20 Gbps
UHBR10 10Gbps

The altera_dp IP includes a maximum line rate selector that requires adjustment to align with the specified value. When you set this value, the width of the interface signals passing between the PHY and protocol core changes. If the PHY and protocol IP link rate settings do not match, the solution does not work correctly.

You cannot automatically detect this issue in your design.

Link-Layer Symbols/Clk 4 4 Defines the number of link-layer symbols transferred with each clock.
Enable Transceiver Toolkit On or Off Off When on, this allows access to debug functions such as eye capture and manual analog parameter settings in the F-tile transceiver, via the Transceiver Toolkit debug environment.
Table 252.  F-Tile DisplayPort PHY IP Receiver and Transmitter Tab Parameters

The PHY configuration setting you select in the IP tab enables the Receiver and Transmitter tabs.

Parameter Values Default Description
Lane 0 physical FGT location in quad 0,1,2,3 3

Defines the physical location of lane 0 in the transceiver quad.

In most cases, you need not change the parameter from the default.

(Rx only)

Lane 1 physical FGT location in quad 0,1,2,3 2

Defines the physical location of lane 1 in the transceiver quad.

In most cases, you need not change the parameter from the default.

(Rx only)

Lane 2 physical FGT location in quad 0,1,2,3 1

Defines the physical location of lane 2 in the transceiver quad.

In most cases, you need not change the parameter from the default.

(Rx only)

Lane 3 physical FGT location in quad 0,1,2,3 0

Defines the physical location of lane 3 in the transceiver quad.

In most cases, you need not change the parameter from the default.

(Rx only)

Channel 0 invert polarity On or off. Off Inverts the output polarity of channel 0
Channel 1 invert polarity On or off. Off Inverts the output polarity of channel 1
Channel 2 invert polarity On or off. Off Inverts the output polarity of channel 2
Channel 3 invert polarity On or off. Off Inverts the output polarity of channel 3
Lane 0 Channel Mapping 0,1,2,3 0 Defines the transceiver channel DisplayPort Lane 0 is mapped to. This parameter depends on the FMC or PCB you are using in your design.
Lane 1 Channel Mapping 0,1,2,3 1 Defines the transceiver channel DisplayPort Lane 1 is mapped to. This parameter depends on the FMC or PCB you are using in your design.
Lane 2 Channel Mapping 0,1,2,3 2 Defines the transceiver channel DisplayPort Lane 2 is mapped to. This parameter dependd on the FMC or PCB you are using in your design.
Lane 3 Channel Mapping 0,1,2,3 3 Defines the transceiver channel DisplayPort Lane 3 is mapped to. This parameter depends on the FMC or PCB you are using in your design.
