7.2. DisplayPort IP Sink Parameters
You set parameters for the sink using the DisplayPort IP parameter editor.
| Parameter | Description |
|---|---|
| Device family | Select the targeted device family: Agilex™ 7, Agilex™ 5E, Stratix® 10, Arria® 10, Cyclone® 10 GX, Arria V GX, Arria V GZ, Cyclone V, or Stratix V. |
| Support DisplayPort sink | Turn on to enable DisplayPort sink. |
| Maximum video output color depth | Determines the maximum video input color depth (bits per color) supported by the DisplayPort source. Select 6, 8, 10, 12 or 16 bpc. DisplayPort sink supports RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 video formats by default. |
| RX maximum link rate | Select the maximum link rate supported: 20 Gbps, 13.5 Gbps, 10 Gbps, 8.1 Gbps, 5.4 Gbps, 2.7 Gbps, or 1.62 Gbps.
Note: Cyclone V devices only support up to 2.7 Gbps. 8.10 Gbps is only available in quad symbols per clock for Arria® 10, Cyclone® 10 GX, Stratix® 10, and Agilex™ 5, Agilex™ 7 devices.
Note: UHBR rates can only be supported in Stratix® 10 and Agilex™ 7 F-Tile devices.
Note: UHBR rate up to 13.5 Gbps can only be supported on Agilex™ 5E devices.
|
| Maximum lane count | Select the maximum lanes supported: 1, 2, or 4.
Note: If you turn on the Support MST parameter, the maximum lane count is fixed to 4 lanes.
|
| Symbol input mode | Determines the RX transceiver data width in symbols per clock. Select dual (20 bits) or quad (40 bits). Dual symbol mode saves logic resource but requires the core to run at twice the clock frequency of quad symbol mode. If timing closure is a problem in the device, you should consider using quad symbol mode.
Note: For 8.1 Gbps and above, this option is limited to Quad (40 bits).
|
| Pixel output mode | Select the number of pixels per clock (single, dual, or quad symbol).
|
| Enable Active Video Data Protocols | Select the following options to configure the type of Video Interface:
Note:
|
| Sink scrambler seed value | Select the initial seed value for the scrambler block.
Note: All DP2.0 link rates limit this to 16’hFFFF.
|
| Export MSA | Turn on to enable the sink to export the MSA interface to the top-level port interface. |
| IEEE OUI | Specify an IEEE organizationally unique identifier (OUI) as part of the DPCD registers. |
| Enable GPU control | Turn on to use an embedded controller to control the sink.
Note: All DP2.0 link rates will require Enable GPU control to be set.
|
| Enable AUX debug stream | Turn on to enable AUX traffic output to an Avalon-ST port. |
| Support CTS test automation | Turn on to support automated test features. |
| Support PRBS Checker | DP2.0 only. Supports PRBS* error checking during Link Quality Test Mode. |
| Support GTC | The Global Time Code (GTC) feature is not available. However, if you want to use this feature, contact your nearest Altera FPGA sales representative or file a Service Request. |
| Support secondary data channel | Turn on to enable secondary data. |
| Support audio data channel | Turn on to enable audio packet decoding.
Note: To use this parameter, you must also turn on Support secondary data channel.
|
| Number of audio data channels | Select the number of audio channels (2 or 8). |
| Support MST | Turn on to enable multi-stream support. You must turn on Enable GPU control to support MST mode.
Note: For multi-stream support, the maximum lane count is fixed to four lanes.
Note: In DP2.0, turn on to enable multiple streams support and set the max stream count accordingly.
|
| Max stream count | Specify the maximum amount of streams supported: 2, 3, or 4.
Note: To use this parameter, you must turn on the Support MST parameter.
|
| Support HDCP 1.3 | Turn on to enable HDCP 1.3 RX support. This parameter can only be used when you specify these settings:
Note:
The Quartus® Prime Pro Edition software does not include the HDCP feature. To access the HDCP feature, contact Altera and quote HSD #18042491442 . |
| Support HDCP 2.3 | Turn on to enable HDCP 2.3 RX support. This parameter can only be used when you specify these settings:
Note:
The Quartus® Prime Pro Edition software does not include the HDCP feature. To access the HDCP feature, contact Altera and quote HSD #18042491442 . |
| Support HDCP Key Management | Turn on to enable HDCP key management support. To use this parameter, you must turn on the Support HDCP 1.3 or Support HDCP 2.3 parameters.
