TUSB321 Swapping of CC1 and CC2 Ports

Other Parts Discussed in Thread: HD3SS3212, TUSB321

Hi,

Is this a mere typo although "DFP Mode Schematic" is mentioned on page 12 of the data sheet, the ports of CC1 and CC2 are swapped as below ?

Could you please tell us that reason it if it is correct ?

Best regards,

Kato

Hello kato-san,

Please notice that the HD3SS3212 has the channel B & C connected to the TX2/RX2 & TX1/RX1 from the Type C connector respectivelly, so it is inverted and it needs to have an inverted control xignal, that's why the CC pins of the TUSB321 are inverted. So it is not a TYPO or an Issue.

Best regards,

Diego.
