For DisplayPort the link is AC
coupled. This shows one way of
doing this otherwise the capacitors
could be moved to a dongle or the
end equipment.

9.2.5 9.1.2 Source Side HDMI/DP Application Using DP-Mode
The TDP158 has a special mode that will allow the device to support either HDMI or DP applications. The device
is put into this mode by setting reg09h[5] to 1. The device will self-configure with the following settings and
become I2C programmable only. The TDP158 does not support automatic Link Training for DisplayPort. AUX
channel bypasses device.
All four lanes are turned on and configured for 5.4 Gbps data rate.
Sets VOD Swing to ~ 410 mV (This value is based upon a VSADJ value of 6 kΩ).
Reg0Ch[7:5] is used to control VOD swing for all lanes.
Reg0Ch[1:0] is used to control Pre-emphasis for all lanes.
Reg30h[7:2] is used to turn on or off individual lanes as well as informing the TDP158 what the data rate is.
This is used for the delay component for Pre-emphasis signal.
