TTIPn1/TRINGn: Transmit Bipolar Tip/Ring for Channel 1~4
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 cor-
responding 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 high impedance (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.

TDn: Transmit Data for Channel 1~4
In Single Rail Mode, the NRZ data to be transmitted is input on these pins. Data on TDn is sampled into the device on the active
edge of TCLKn. The active edge of TCLKn is selected by the TCLK_SEL bit (TCF0, 02H...). Data is encoded by AMI, HDB3 or
B8ZS line code rules before being transmitted to the line. In this mode, TDNn should be connected to ground.
TDPn/TDNn: Positive/Negative Transmit Data for Channel 1~4
In Dual Rail Mode, the NRZ data to be transmitted is input on these pins. Data on TDPn/TDNn is sampled into the device on
the active edge of TCLKn. The active edge of the TCLKn is selected by the TCLK_SEL bit (TCF0, 02H...) The line code in Dual
Rail Mode is as follows:

TCLKn: Transmit Clock for Channel 1~4
These pins input 1.544 MHz for T1/J1 mode or 2.048 MHz for E1 mode transmit clock. The transmit data on TDn/TDPn or TDNn
is sampled into the device on the active edge of TCLKn. If TCLKn is missing3 and the TCLKn missing interrupt is not masked,
an interrupt will be generated.

Notes:
1. The footprint ‘n’ (n = 1~4) represents one of the four channels.
2. The name and address of the registers that contain the preceding bit. Only the address of channel 1 register is listed, the rest addresses are represented by '...'. Users can find
these omitted addresses in the Register Description section.
3. TCLKn missing: the state of TCLKn continues to be high level or low level over 70 clock cycles.
