8.2.16 DisplayPort

The TDP1204 supports DisplayPort at datarates up to 8.1 Gbps (HBR3) when configured for either pin-strap and I2C mode. In pin-strap mode, DisplayPort mode is enabled as provided in Table 8-18. In I2C mode, DisplayPort mode is enabled when FRL_RATE field (offset 0x31) is programmed to 0x6, RATE_SNOOP_CTRL (offset 0xA bit 2) is disabled, and TXFFE_SNOOP_CTLE (offset 0xA bits 1:0) is disabled.

Note: The TDP1204 must be configured as a linear redriver when enabled for DisplayPort mode. The linear range should be programmed to highest level (Dx_VOD = 0x3 and CLK_VOD = 0x3). The TDP1204 TX termination must be set to 100-ohms (TERM = 0x3) and TX bias must be set to ac-coupled (TX_AC_EN = 0x1).
