8.4.1 Repeater Mode

Upon de-assertion of RESETB or software reset and after t_RH_READY or t_RS_READY, the TUSB2E11 enables and enters the default state. In the default state, the TUSB2E11 is ready to accept eUSB2 packets, RAP, and I2C requests. The repeater will either be in host repeater mode or peripheral repeater mode depending on the receipt of either host mode enable or peripheral mode enable.

When the TUSB2E11 is repeating high-speed packets, either from eUSB2 to USB 2.0 or from USB 2.0 to eUSB2, up to 4UI (may include partial UI) of HS SOP can be truncated. This is the same as a standard USB 2.0 HUB operating in high speed mode which can truncate up to 4UI.

When the TUSB2E11 is repeating high-speed packets from eUSB2 to USB 2.0, up to 1.6UI of random dribble bits (may include partial UI) can be introduced after HS EOP. This is the less than a standard USB 2.0 HUB operating in high speed mode which can have up to 4UI of random dribble bits.

When the TUSB2E11 is repeating high-speed packets from USB 2.0 to eUSB2, up to 5UI of random dribble bits (may include partial UI) can be introduced after HS EOP. This is more than a standard USB 2.0 HUB operating in high speed mode which can have up to 4UI of random dribble bits. eDSPr/eUSPr receiving eUSB2 high-speed packets should ignore 5UI of dribble bits after detecting no stuffed bit insertion indicating HS EOP.
