Hi Team,
Customer is using TMDS181.
Would you please recommend the proper solution for this?
After pull-high pine 1，is there any application limitation if customer want to swap lane & polarity?
8.3.3 Swap and Polarity Working
TMDS181 incorporates swap function, which can set the input lanes in swap mode. The IN_D2 routes to the
OUT_CLK position. The IN_D1 swaps with IN_D0. The swap function only changes the input pins. The EQ setup
follows the new mapping (see Figure 26). This function can be used with the SWAP/POL pin 1 and control the
register 0x09h bit 7 for SWAP enable. Lane swap function works in both redriver and retimer mode.
The TMDS181 can also swap the input polarity signals. When SWAP/POL is high the n and p pins on each lane
will swap. Polarity swap only works when in retimer mode. Take care when this function is enabled and the
device is in automatic crossover mode between redriver and retimer modes. When the data rate drops to the
redriver level, the polarity swap is lost.
