TTIPn
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, 23H...)
TRINGn in the corresponding channel is set to high impedance state.
In summary, these pins will become high impedance in the following conditions:
•
•
•
•
•
•
RTIPn/RRINGn: Receive Bipolar Tip/Ring for Channel 1~8
These pins are the differential line receiver inputs.
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 inter-
nal 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.
