TTIPn1/TRINGn: Transmit Bipolar Tip/Ring for Channel 1~8
These pins are the differential line driver outputs and can be set to high impedance state globally or
individually. A logic high on THZ pin turns all these pins into high impedance state. When THZ bit
(TCF1, 03H...)2 is set to ‘1’, the TTIPn/TRINGn in the corresponding channel is set to high impedance
state.
In summary, these pins will become high impedance in the following conditions:
THZ pin is high: all TTIPn/TRINGn enter high impedance;
THZn bit is set to 1: the corresponding TTIPn/TRINGn become high impedance;
Loss of MCLK: all TTIPn/TRINGn pins become high impedance;
Loss of TCLKn: the corresponding TTIPn/TRINGn become HZ (exceptions: Remote Loopback;
Transmit internal pattern by MCLK);
Transmitter path power down: the corresponding TTIPn/TRINGn become high impedance;
After software reset; pin reset and power on: all TTIPn/TRINGn enter high impedance.
