Can I safely assume that it matches the link rate shown on Wikipedia for display port[1]? I.e. RBR (Reduced Bit Rate): 1.62 Gbit/s bandwidth per lane (162 MHz link symbol rate) HBR (High Bit Rate): 2.70 Gbit/s bandwidth per lane (270 MHz link symbol rate) HBR2 (High Bit Rate 2): 5.40 Gbit/s bandwidth per lane (540 MHz link symbol rate), introduced in DP 1.2 HBR3 (High Bit Rate 3): 8.10 Gbit/s bandwidth per lane (810 MHz link symbol rate), introduced in DP 1.3 So then they're MHz but the table is written in kHz when it should be written in Hz. Either way, the table can be removed and then we just need to fix the DP PHY PLL code to accept Hz instead of kHz. [1] https://en.wikipedia.org/wiki/DisplayPort#Main_link
