Figure 6-9. Digital Loopback
6.8.3
The inputs at RTIPn and RRINGn are looped back to TTIPn and TRINGn. The inputs at TPOSn, and TNEGn are
ignored during a remote loopback. While the TCLKn pin is ignored in remote loopback mode for the data path, the
TCLKn pin must have an active signal applied in order to keep the transmitter operational. See the TCLKn pin
description for details. This loopback is conceptually shown in
Figure 6-10. Remote Loopback
