SN65DSI86: eDP compatibility and resolution support limitation

Part Number: SN65DSI86

Hello expert,

My customer has some questions below.

1)     Can SN65DSI86 support eDP 1.4? --> after checking with E2E, I found eDP 1.4 is okay for SN65DSI86 but without PSR feature. correct me if it's wrong.

2)     They only use SN65DSI86 Front-End (MIPI-DSI) for single-channel (4-lane). Based on this connection,how high could eDP panel resolution reach?

3)     They will use two eDP panels, spec is shown below. Could SN65DSI86 (Front-End – Single channel MIPI-DSI) support below panel spec?

  • 1920 x 3(RGB) x 1080, 2-lane eDP1.2
  • 1920 x 3(RGB) x 1080, 4-lane eDP1.4

Best regards,

Ann Lien

    1. The DSI86 still supports the PSR, but it will not support the new PSR feature introduced in the eDP1.4 spec. eDP v1. 4 addresses system power reduction through new features, including a new partial-frame update capability for Panel Self Refresh (PSR), lower interface voltage swings, additional link rate options, transport data compression, and regional backlight control.

    2. From the data throughput calculation, the DSI86 will support the 1920x1080 panel.

    Thanks
